Question

question 9 of 10 what is the value of x? a. 144° b. 14° c. 56° d. 36°

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, $x + 65+79 = 180$.

Step2: Solve for x

$x=180-(65 + 79)$.
First, calculate $65 + 79=144$. Then, $x = 180 - 144=36$.

Answer:

D. 36°
