Question

What is the value of x?

Answer 1

x=8

Explanation:

This triangle is an equilateral one, and so all three angles are the same; their measure is 60 degrees each. Thus, 7x + 4 = 60, or 7x = 56.

x comes out to 8.

Answer 2

x=8

Explanation:

this is an equilateral triangle, which means all sides are equal

if all the sides are equal, all the angles are equal

the three angles are all equal to 60 degrees (180/3 = 60)

7x+4 = 60

subtract 4 from each side

7x = 56

divide by 7 on each side

x = 8
