Answer:
A. 62 degrees
Step-by-step explanation:
The line m is straight, therefore its value is 180. So, the angle addition postulate tells us that x+118=180. To solve subtract 118 from both sides, x+118-118=180-118, which simplifies to x=62.
B
If you don't understand, you can ask.
(x+6)(x+6)
(x+6)^2
Always remember this identity
(a+b)^2 = a^2 + b^2 + 2ab
So, Now take x=a , 6 =b
Substitute above values
x^2 + 36 +2(x)(6)
=x^2 +36 +12x
=x(x+12) +36
