Question

Please help answer the following question

Answer 1

D

Explanation:

The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).

<2 + 40 + 40 = 180 Combine the left

<2 + 80 = 180 Subtract 80 from both sides

<2 = 180 - 80

<2 = 100 degrees.

That's not the answer. We have to solve for x

<2 = x + 106

100 = x + 106 Subtract 106 from both sides

100 - 106 = x

x = - 6
