Answer:

Step-by-step explanation:

Supplementary angles are 180 in total, so to find the answer you do 180-10, which equals 170. The answer is 170
X² = 17
To simplify this, you need to find the square root of x², which is x, and the square root of 17.
x = √17
Also remember that when you are using square root, the answer can be either positive or negative.
x = +/-√17 ≈ +/- 4.12
