Question

What is the value of x

Answer 1

x = 8

Explanation:

An equilateral triangle has all sides and angles the same. An equilateral triangle has 60° measure on all verticals.

So,

7x + 4 = 60

7x = 60 - 4

7x = 56

x = 8

Check:

7(8) + 4 = 60

56 + 4 = 60

60 = 60

Answer 2

Answer:x=8

Explanation:

The image shows an equilateral triangle

In geometry, an equilateral triangle is a triangle in which all three sides are equal, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

Therefore,

(7x+4)°=60°.

7x+4=60

7x=60-4

7x=56

7x/7=56/7

x=8
