Answer:
it would be c
Step-by-step explanation:
Step-by-step explanation:
- Angle UQN = Angle QNM, in alternate interior angle relation
- so Angle QNM will be x.
- Now we know that the angles inside a triangle sum up to give 180⁰,that is x+x+42⁰=180⁰
2x+42⁰=180⁰
2x=180⁰- 42⁰
2x= 138⁰
x= 138⁰/2
x= 69⁰
Find n first.
n+10= 40
Subtract 10.
n= 30
Plug in n.
30-25= 5
The answer is 5.
I hope this helps!

Answer:
c and c
Step-by-step explanation:
the first one is because if you graph this this line goes striaght up and down and and that cant happen in a function and the second one I dont know how explain
Step-by-step explanation:
straight angle a + 117 = 180
a = 180 - 117
= 63
total angle in triangle = 180
63 + b + 81 = 180
b = 180 - 63 - 81
= 36
