Step-by-step explanation:
diagonals of the rhombus bisect each other at right angles .
5a = 90
a = 90/5 = 18
in ∆ OCD:
5a + 2a + b = 180
7a+ b = 180
b = 180 - 7 ( 18)
b = 180 - 126
b = 54 °

Answer:
a = 18°
[tex] b= 108\degree [/tex]
Step-by-step explanation:
ABCD is a rhombus.
AC and BD are its diagonals
Diagonals of a rhombus bisects at right angles.
Therefore,
5a = 90°
a = 90°/5
a = 18°
2a = 2*18° = 36°
Diagonals of a rhombus bisects the opposite angles.
Therefore,
[tex] m\angle ADC = 2(2a)[/tex]
[tex] m\angle ADC = 2\times 36\degree [/tex]
[tex] m\angle ADC = 72\degree [/tex]
[tex] m\angle ADC+m\angle DCB= 180\degree [/tex]
(Adjacent angles of a rhombus are supplementary)
[tex] 72\degree+b= 180\degree [/tex]
[tex] b= 180\degree-72\degree [/tex]
[tex] b= 108\degree [/tex]

Tom and Katie are discussing the sequence: 22, 17, 12, 7, 2
Tom says the nth term rule is: -5n+17
Katie says the nth term rule is: 27-5n
A)Only Tom is correct
B)Only Katie is correct
C)They both are correct
D)Neither are correct
Answers
Answer:
B
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 22 and d = - 5, then
[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B
What is the area of the figure below?
Answers
Answer:
104
Explanation:
1. Split the figure by the line the larger portion creates.
2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.
3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.
4. Now, we simply do 6 · 8 = 48. Almost there!
5. Finally, add the values of the left side and the right side (48 + 56 = 104)
6. YOUR ANSWER IS 104 cm squared.
the difference of products of a fraction with 5 whole 7/8 and 3 whole 3/4 is 11.Find the fraction.
Answers
Answer:
88/17
Step-by-step explanation:
5x · 7/8 - 3x · 3/4 = 11
35x/8 - 18x/8 = 17x/8
17x/8 = 11
17x = 88
x = 88/17

Yes
Step-by-step explanation:
Angle sum property=180°
The first triangle = 105°+40° = 145°= 180-145=35
The second triangle = 105°+35°=140°=180-140=40
So both are same
Try to find the third angle in both triangles and if the angles of both triangles are same, it means the triangles are similar

If one event impacts the probability of a second event occurring, than which of the following is true?
The events are complements.
The events are dependent.
The events are independent.
Answers
Answer:
The events are dependent.
Step-by-step explanation:
Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur. If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.

Answer:
The answer: ( 2 , -3 )
Step-by-step explanation:
equation (1): 5x + 2y = 4
equation (2): y = x - 5
step1: sub ( x-5 ) for y in equation 1:
5x + 2 ( x-5 ) = 4
step2: multiply 2 by the bracket:
5x + 2x - 10 =4
step3: add the x term together:
7x - 10 = 4
step4: add 10 for both sides:
7x = 14
step5: divide by 7 from both sides to get the value of x:
x = 2
step6: sub ( 2 ) for x in equation 2 :
y = x - 5
y = 2 - 5
step7: simplify to get the value of y:
y = -3
So the answer is:
x = 2 and y = -3
( 2 , -3 )

Step-by-step explanation:
It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

Answer:
3rd answer choice
Step-by-step explanation:
Any time you have a proportion, the two ratios have to match, so 32 and x+8 are the bases, so you need to length of the side of those bases, 20 is the length of the base for the 32, but notice how 5 is not the side for x+8, therefore, 20-5 = 15, so 15 is the side adjacent to the base x+8, and they are in the right order small side / big side = small base / big base

Answers
The another way is same as;
Multiplying by 0.5 with original price.
Here,
A shop owner increases some prices by 50%.
We have to find another method to find same condition.
What is the percentage?
A relative value indicating hundredth parts of any quantity is called the percentage.
Now,
A shop owner increases some prices by 50%.
Let the original price is x.
Then, The increase value = x * 50% = x * 50/100 = 0.5x
Hence, To find the increase value we have to multiply by 0.5 with original price.
