Question

What is the value of x

Answer 1

Problem: A triangle as two angles that measures 35 degrees, and 70 degrees.


Find the measure of the third angle: The sum of the three interior angles of a triangle adds up to 180 degrees.

35 degrees + 70 degrees + x = 180 degrees

35 + 70 = 105
105 + x = 180 degrees

Find the value of X:
x = 180 degrees - 105 degrees
x = 75 degrees

Answer: The third angle of the triangle measures 75 degrees





Hope that helps!!!

Answer 2

All angles in a triangle have to add up to 180. You already know one is 35 and the other 70. So we do

70 + 35 + x = 180
70 + 35
105 + x = 180
-105 -105

x = 75
