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

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

Answer: Could be 0,1,2,3,4,5

Step-by-step explanation: 9-n has to be greater or equal to four. 9 minus 4 is five. So all of the answers must be positive numbers that are less than five.

Answer:

the first one is proportional because you could multiply by 4

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.

Answer:

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

Answer:

s = 18

Step-by-step explanation:

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]

Answer: 13.B

17.D

18.A

Step-by-step explanation:

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.

I'm sorry if this doesn't make sense, but I hope I helped out

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.

Answer: A. (It’s 25)

Step-by-step explanation:

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]
