Question

true or false: given the kite below, the value of x = -11. select one: true false

Explanation:

Step1: Recall angle - sum property of a triangle

In a triangle, the sum of interior angles is 180°. Consider the triangle with angles 35°, 14° and (21 - 10x)°.
So, 35+14+(21 - 10x)=180.

Step2: Simplify the left - hand side

First, add the constant terms: 35 + 14+21=70.
The equation becomes 70-10x = 180.

Step3: Solve for x

Subtract 70 from both sides: - 10x=180 - 70.
-10x = 110.
Divide both sides by - 10: x=-11.

Answer:

True
