UTR is an equilateral triangle and RTS is isosceles.

UT = TR = RS

x - 7 = 11

x = **18**

The angles in triangle RTS add up to 180 degrees.

5y + 5y + 120 = 180

10y = 60

y = **6**

Triangle UTR is an equilateral triangle so all of its angles are equal to 60 and all of its sides are equal. TR =11 because triangle TRS is an isosceles triangle.

Therefore, x - 7 = 11

**x = 18**

180 - 60 = 120 so angle TRS = 120

180 - 120 = 60

60/2 = 30

Therefore, 5y = 30

**y = 6**
