Question

What does “x” equal ?

Answer 1

62 degrees.

Explanation:

This is an isosceles triangle ( 2 sides are equal) so the 2 base angles are also equal.

x = (180 - 56) / 2

= 124 / 2

= 62 degrees.

Answer 2

x = 62

Explanation:

Since 2 sides are congruent then the triangle is isosceles.

Thus the 2 base angles are congruent.

The sum of the 3 angles = 180°

x =
`(180-56)/(2)` =
`(124)/(2)` = 62
