Question

question 6 of 10
what is the value of x?
a. 150°
b. 50°
c. 100°
d. 30°

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of interior angles of a triangle is 180°.

Step2: Set up an equation

Let the three angles of the triangle be 50°, 100°, and x°. Then 50 + 100+x=180.

Step3: Solve the equation for x

First, simplify the left - hand side: 150 + x=180. Then subtract 150 from both sides: x=180 - 150. So, x = 30.

Answer:

D. 30°
