Question

Can anybody help? Thank you.

Answer 1

We need to set up an equation where all 3 terms (x, 55°, and 40°) add up to equal 180.

Here is how we do it:

`x + 55 + 40 = 180\\\\x + 95 = 180\\\\x = 85`

The answer is B: 85°.

Answer 2

The second answer choice, 85

Explanation:

That is a 180 degree angle, and the entire angle must add up to 180 degrees. 55+40=95, 95+85=180
