What is 1/2(4+8x)+22=180

X=39

Step-by-step explanation:

1/2×(4+8x)+22=180 (factor expression)

1/2×2(2+4x)+22=180. (Reduce)

(2+4x)+22=180 (rewrite expression)

2+4x+22=180 (calculate)

24+4x=180 (move constant to right)

4x=180-24 (calculate)

4x=156 (divide both sides)

X=39

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
