Question

Can someone please help me?? trying to retake some questions

If angle U = 8x + 9 degrees, and angle W = 8x - 5 degrees, then the measure of angle U is ___ degrees.

Answer 1

97 degrees

Explanation:

We know that U and W add up to 180 degrees so we can write:

8x+9+8x-5=180

Simplify:

16x+4=180

We can figure out x from here!

x=11

Since x=11, we can plug that in and get:

88+9=97
