Answer:
x= 50
Step-by-step explanation:
the total measure of all the angles of a triangle is always 180 so you subtract 65 two times (once for each of the other angles) and that will ive you the remaining degrees which in the case would be x.
1. 180 = triangle
2, 180- 65- 65= 50
3. x=50
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
