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

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
