Question

Find the value x given angles? ​

Answer 1

x=60

Explanation:

180 is the some of the angle of an triangle

in the left triangle the angle is = 180-70-75=35

in the right triangle the angle is=180-35-60=85

x=180-80-45=60

Answer 2

Explanation:

Remember: The three interior angles of a triangle will always add up to 180 degrees.

In order to solve for x, we need to solve for other missing angles

1) Solve for the missing angle on the triangle to the left.

180 - 75 -70 = 35 degrees.

2) Solve for the missing angle on the triangle to the right (not x).

180 - 60 - 35 = 85 degrees

3) Finally, solve for the x angle by subtracting 45 and 85 from 180. x = 50 degrees.
