Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
Answer: N = 5
Step-by-step explanation:
M = 3N + 4R
M = 43
R = 7
Replacing by the values
43 = 3N + 4*7
43 = 3N + 28
43-28 = 3N
3N = 15
N = 15/3
N = 5
Just use your right angled triangle formula.
A=
![\frac{ab}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bab%7D%7B2%7D%20)
Plug n chug
A=
![\frac{11*13}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11%2A13%7D%7B2%7D%20)
A=71.5
You could make them have the same denominator, making it 7/10-5/10=2/10.
The answer is 2/10, or simplified, 1/5.
