Question

Find the value of x *20 points*

Answer 1

Answer:

The answer to your question is x = 40°

Step-by-step 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°
