Answer:
y*y*y*y*y*y
Step-by-step explanation:

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.
I have no clue you have to do something like x2-x1 over y1-y2 and you get yoyu answer from that.
