Anyone plz help me ty
Answer:
it would be an acute angle because it is less than 90
Answer:
It would be a right triangle
Step-by-step explanation:
A triangle must always have 3 angles that add up to 180°.
So if two angles are 45°, then the last angle has to add along with the 45° angles to equal 180°.
If you multiply 45 × 2 (since there are two angles that are 45°), you get 90, which is half of 180.
Also a 90° angle is a right angle, which would help you out with remembering.

Choose the appropriate value for x for the following similar triangles given below.
Answer: A. (It’s 25)
Step-by-step explanation:
find the value of x
Answer:
x = 12
Step-by-step explanation:
In a pair of intersecting lines the vertically opposite angles are equal.
[tex] \longrightarrow [/tex] (6x + 7)° = (8x - 17)°
[tex] \longrightarrow [/tex] 6x + 7 = 8x - 17
Subtract 8x + 7 from both sides:
[tex] \longrightarrow [/tex] 6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)
[tex] \longrightarrow [/tex] (6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)
6x - 8x = -2x:
[tex] \longrightarrow [/tex] -2x + (7 - 7) = (8x - 8x) + (-17 - 7)
7 - 7 = 0:
[tex] \longrightarrow [/tex] -2x = (8x - 8x) + (-17 - 7)
8x - 8x = 0:
[tex] \longrightarrow [/tex] -2x = -17 - 7
-17 - 7 = -24:
[tex] \longrightarrow [/tex] -2x = -24
Divide both sides by -2:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{-2x}{-2} = \dfrac{-24}{-2} [/tex]
[tex] \sf \dfrac{-2}{-2} = 1 [/tex]
[tex] \longrightarrow [/tex] [tex] \sf x = \dfrac{-24}{-2} [/tex]
[tex] \sf \dfrac{-24}{-2} = 12 [/tex]
[tex] \longrightarrow [/tex] x = 12
baker has 5\dfrac145 4 1 5, start fraction, 1, divided by, 4, end fraction pies in her shop. She cut the pies in pieces that are each \dfrac18 8 1 start fraction, 1, divided by, 8, end fraction of a whole pie.
Answer:
The answer is "She cut a total of 42 pieces of pie".
Step-by-step explanation:
Given :
Total pie= [tex]5 \frac{1}{4}[/tex]
cut pie = [tex]\frac{1}{8}[/tex]
The number of pieces of the pie she has=?
Solve the mixed fraction value:
[tex]\to 5 \frac{1}{4}= \frac{21}{4}[/tex]
If she cuts the pieces into the entire pie, that is = [tex]\frac{1}{8}[/tex]
So, the equation is:
[tex]\to \frac{21}{4} = \frac{1}{8} \times x[/tex]
[tex]\to x= \frac{21 \times 8}{4}\\\\ \to x= 21 \times 2\\\\ \to x=42[/tex]

(a) the probability that a vampire bat would pick A (b) the probability that a vampire bat would pick C (c) the probability that a vampire bat would pick T
Answer:
See Explanation
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have that:
[tex]A = 71[/tex]
[tex]C = 121[/tex]
[tex]T = 66[/tex]
First, we calculate the total
[tex]Total = A + C + T[/tex]
[tex]Total = 71 + 121 + 66[/tex]
[tex]Total = 258[/tex]
Solving (a): Probability of A
This is calculated using:
[tex]Probability = \frac{A}{Total}[/tex]
[tex]Probability = \frac{71}{258}[/tex]
[tex]Probability = 0.275[/tex]
Solving (b): Probability of C
This is calculated using:
[tex]Probability = \frac{C}{Total}[/tex]
[tex]Probability = \frac{121}{258}[/tex]
[tex]Probability = 0.469[/tex]
Solving (b): Probability of T
This is calculated using:
[tex]Probability = \frac{T}{Total}[/tex]
[tex]Probability = \frac{66}{258}[/tex]
[tex]Probability = 0.256[/tex]

Which of the following transformations is the only one that can change the lengths of its sides but remain similar??
A) Translation
B) Rotation
C) Reflection
D) Dilation
Answer:
D
Step-by-step explanation:
It is dilation because transformation is moving and sliding, rotation is spinning, reflection is a mirroring of the shape upon a certain line or axis, and dilation is the change in size leaving 1 point the same.

Option C
Step-by-step explanation:
Since it's draining, it means it must start at a certain value and end at a maximum of 0 since water cannot ever be less than 0. Since it's original amount is 40, it can only start draining from 40 and end at max 0 hence 0 ≤ y ≤ 40

Find each percent increase. Round to the nearest percent.
From 5 miles to 16 miles
I need the increase in percentage
Answer:
220%
Step-by-step explanation:
[tex]Percentage\ Increase/Decrease=\frac{Final\ Quantity\ - Initial\ Quantity}{Initial\ Quantity} *100\\Percentage\ Increase/Decrease=\frac{16-5}{5}*100\\=11*20\\=220\ \%[/tex]
As Final quantity is larger than the Initial Quantity, the net percent is an increase.
3. Priya says, "I know everything about a right triangle with a 30 degree angle and a hypotenuse with length 1 cm. Here look." The other angle is 60 degrees. The leg adjacent to the 30 degree angle 0.866 cm long. The side opposite the 30 degree angle is 0.5 cm long. Han asks, "What would happen if a right triangle with a 30 degree angle has a hypotenuse that is 2 cm instead?" Help them find the missing angles and side lengths in the new triangle. Explain or show your reasoning.
Answer:
1) The measure of the third angle is 60°
2) The length of the opposite side to the angle 30° is 1 cm
3) The length of the opposite side to the third angle 60° is approximately 1.732 cm
Step-by-step explanation:
1) The given parameters are;
The known angle of a right triangle = 30°
The length of the hypotenuse = 2 cm
Given that the triangle = A right triangle, with one of the interior angles = 90°, we have;
The measure of the third angle = 180° - 90° - 30° = 60°
The measure of the third angle = 60°
2) We have that sin(30°) = 0.5 = (The length of the opposite side to the angle 30°)/(The length of the hypotenuse side)
0.5 = (The length of the opposite side to the angle 30°)/(2 cm)
∴ The length of the opposite side to the angle 30° = 2 cm × 0.5 = 1 cm
The length of the opposite side to the angle 30° = 1 cm
3) Similarly, the length of the opposite side to the third angle 60° = sin(60°) × (The length of the hypotenuse side)
∴ The length of the opposite side to the third angle 60° = (√3)/2 × 2 cm = √3 cm
The length of the opposite side to the third angle 60° = √3 cm ≈ 1.732 cm
