1.

The following triangle is equilateral triangle.
Find the measures of r and y.
(2x +10)
(3y +3)

Answer 1

Answer: x=25, y=19

Step-by-step explanation: Because the triangle is equilateral, all the angles must be equal to 60 degrees. So 2x+10=60. 2x=50 and x=25. Then the same thing: 3y+3=60. 3y=57, y=19.
