Answer:

The value of x is 3

The value of y is 5

Step-by-step explanation:

Given triangle STU is Equilateral triangle.

Angle S = 25y-15

Angle U = 20x

Since, Triangle STU is Equilateral triangle.

Angle S =Angle T =Angle U = 60

For value of x:

Angle U = 20x and Angle U = 60

We can write as

20x=60

x=3

For value of y:

Angle S = 25y-15 and Angle S = 60

We can write as

25y-15=60

25y=60+15

25y=75

y=5

As the all sides are equal , each angle is 60⁰ and ita an equilateral triangle

Thus :

20x = 60

x = 3

25y - 15 = 60

25y = 75

y = 3
