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

Answer:

55°

Step-by-step 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°  = $\frac{110}{2}$  = 55°
