Question

Find the value of x in the triangle shown below.
x=

Answer 1

x = 61°

Explanation:

From the image, we can see that we have an isosceles triangle.

We know that the other 2 angles will be equivalent to each other.

We also know that the sum of angles in a triangle adds up to 180°.

Step 1: Set up equation

58 + x + x = 180

Step 2: Solve

58 + 2x = 180

2x = 122

x = 61°
