Question

The following is an equilateral triangle. Solve for y.

(y-8)°
A) 57 Degrees
B) 60 Degrees
C) 68 Degrees
D) 72 Degrees

Answer 1

y = 68 degrees

Explanation:

Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8

If one of the angles is y-8, then the rest are y-8 too

mathematically, by adding all , we have a total of 180

Thus;

3(y-8) = 180

y-8 = 180/3

y-8 = 60

y = 60+8

y = 68 degrees
