The answer is 10 because all the angles are equal making it a equilateral triangle.
Therefore, the sides are all equal to one another, 3x - 8 = 5x - 20.
You just solve for x and get 6. You then plug in 6 for x and evauluate the equation, getting 10.
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
hope this helps!
I solved it this way. I’m guessing you should replace the zeros with these numbers here.
