Answer:
x = 18
y = 6
Step-by-step explanation:
The angle marks tell you that ΔTRS is isosceles, so RT ≅ RS. Similarly, the angle marks tell you ΔTRU is equilateral, so UT ≅ RT. This means ...
x - 7 = 11
x = 18 . . . . . . add 7
__
Angle URT is an exterior angle equal to the sum of congruent angles RTS and RST. This means ...
∠RTS = (1/2)∠URT = 30° . . . . . angles in an equilateral triangle are 60°
5y° = 30°
y = 6 . . . . . . divide by 5°
