Question

Find the value of x in the triangle shown below

Answer 1

x = 62

Explanation:

The triangle is isosceles. That means two sides are equal. The angles opposite those equal sides are also equal.

Every triangle has 180 degrees.

The unmarked angle is also x.

x + x + 56 = 180 Combine the left

2x + 56 = 180 Subtract 56 from both sides

2x = 180 - 56

2x = 124 Divide by 2

2x/2 = 124/2

x = 62
