Answer:
R is 51 degrees
P is 51 degrees
Q is 78 degrees
Explanation:
This is an isosceles triangle so R and P are the same angle degree.
First set them equal to each other to be (4x+23)=(2x+37) to get x=7.
Substitute X with 7: 4(7)+23=2(7)+37. It will be 51=51.
A triangle is equal to 180 degrees so 51+51 is 102 and 180-102 is 78.
Hope this helped :)
