Question

Need a little help on this

Answer 1

This triangle has two same long sides, Therefore, the two unknown angles have the same value

triangle total angle value = 180°
180° - 56° = 124° : 2 = 62°

Answer 2

Explanation:

This is an isosceles triangle. You can tell because 2 of the sides are equal and the third is not equal to either of the other two.

x + x + 56 = 180 Combine the left

2x + 56 = 180 Subtract 56 from both sides.

2x = 180 - 56

2x = 124 Divide by 2

x = 124/2

x = 62
