Question

Solve for x in the following figure. Choose the appropriate result.

Answer 1

Answer:

d

Step-by-step explanation:

all of the angles add up to equal 180 so we setup the equation as 45+3x=180

first you subtract each side by 45

135=3x

then you divide each side by 3 and get that

x=45

Answer 2

Answer:

D, 45°

Step-by-step explanation:

at $x=45$

the resulting angles would be $45, 90, 45$ and these add up to $180$°
