Question

9. Solve for x: Please explain

Answer 1

x = 70°

Explanation:

Since 2 sides are marked as congruent then the triangle is isosceles with 2 base angles being congruent , both 55°

the sum of the 3 angles in the triangle = 180° , so

x + 55° + 55° = 180°

x + 110° = 180° ( subtract 110° from both sides )

x = 70°

Answer 2

since the triangle has a line on 2 sides, it means that it is equal. Also, every triangle has 180 degrees so the missing degree is 70
