Question

Find the value of x in the triangle shown below. This question is Find angles in isosceles triangles.​

Answer 1

x = 56

Explanation:

Since two sides of the triangle have the same length, we knows it's isosceles. This means we we will have two base angles with the same value. Since x is the angle in between both legs, we knows x is the vertex angle.

62 is a base angle, which means the other base will be 62 as well. And since the angles of a triangle always add up to 180,

x = 180 - (62 + 62)

x = 180 - 124

x = 56
