Answer:
x = 12
Step-by-step explanation:
The diagram shows an equilateral triangle (because all angles are congruent). All sides in equilateral triangle are congruent, so

Solve the equation

Check this value:

Thus, 
The answer is 20in. You multiply 4 by 5 because 5x5 is 25 so the answer is 20
the answer is b because x is greater than or equal to 0
76 -20 = 56 so then you do 56/8 which is 7
So 7 is the answer Hope this helps
