Question

What is the value of x?

x = 45°
x = 65°
x = 70°
x = 115°

Answer 1

65 degrees.

Step-by-step explanation: You can add 45 and 70 to get 115 degrees. Then, you subtract 180 degrees by 115 degrees to get 65 degrees.

Answer 2

The three inside angles of a triangle need to equal 180 degrees.

To find X subtract the two known angles from 180.

X = 180 - 45 - 70

X = 65 degrees.
