B. 
first set it equal to zero: 
3x^2-36 = 0
add 36 to both sides:

divide by 3 to both sides:
x^2=12
take the square root of 12 and you get factors of 2,2, and 3, so you're answer is b.

What is the measure of x in degrees ?
mr Goodwill [35]

Answer:

x = 35°

Step-by-step explanation:

Same side interior angles are supplementary, or they add up to 180°. So write an equation:

x+145=180

Solve for x. Subtract 145 from both sides:

x+145-145=180-145\\\\x=35

The value of x is 35°.
