Answer:

The answer to your question is x = 40°

Explanation:

According to the picture we determine that the triangle to the right is isosceles so two of its angles are equal.

Remember that the sum of the internal angles in a triangle equals 180°

2x° + 100° = 180

- Subtract 100 in both sides

2x + 100 - 100 = 180 - 100

- Simplify

2x = 80

-Divide both sides by 2

2/2 x = 80/2

Simplify and result

x = 40°
