Question

A clothes hanger is in the shape on an isosceles triangle. If the hanger is 70° wide what are the base angles?

Answer 1

55°

Explanation:

Given parameters:

Angles in the triangle;

70°, X° and X°

The triangle is an isosceles triangle;

In all triangles, the sum of the interior angles is 180°

So;

70° + X° + X° = 180°

70° + 2X° = 180°

2X° = 180° - 70°

2X° = 110°

X° =
`(110)/(2)` = 55°
