Question

Find the value of x. Sum 1 help I rlly don’t get this

Answer 1

Answer:

x = 12 degrees

Step-by-step explanation:

This isosceles triangle has two equal sides and thus two equal angles.  We find the measure of angle 2 by subtracting 76 degrees from 180 degrees, and then dividing the result (104 degrees) by 2:  m<2 = 52 degrees.

Then m<2 = 52 degrees = 3x + 16, or

                    52 degrees - 16 degrees = 3x, or:

                     36 degrees = 3x

Thus, x = 12 degrees
