Question

Find the value of x and y.

Answer 1

Explanation:

if two angles are 60 degrees, the third one is also 60 degrees

that means all the sides are equal

if one side is 4x

4x+4x+4x=54

12x=54

x=4.5

Answer 2

This is a triangle with 2 equal angles and equal to 60

=> this is an equilateral triangle

=> y = 60

4x.3 = 54

=> y = 60

x = 54/12 = 4.5
