x =

Answer 1

x = 25

Explanation:

from the drawing we understand that it is an equilateral triangle, 3 angles marked as congruent, therefore the sides are also equal, therefore

4x - 30 = 2x + 20

2x = 50

x = 50 : 2

x = 25

--------------

4(25) - 30 = 2(25) + 20

100 - 30 = 50 + 20

70 = 70

same value the answer is good
