Question

Each angle of the equilateral triangle in the figure has measure (2x + 12)°. Find the value of x. answers: 24 39 12 84

Answer 1

2x+12=60

2x=60-12

2x=48

x=24

Explanation:

Equilateral triangles have equivalent angles each of 60°

Answer 2

24

Explanation:

Equilateral has 3 angles that add up to 180, and all angles are equal

3(2x+12) = 180

6x+36 = 180

180-36 = 6x

144 = 6x

24 = x
