Help Asap!use the triangle sum theorem to solve for x in the triangle.

X = -12

90 + 70 + x + 32 = 180
192 + x = 180
-192 -192
————————-
x = -12

hope this helps :)

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
