Answer:
∡QPR=126
x=13
Explanation:
Since its a triangle and there is three side the sum of the angles equal 180 degrees.
So that means:
180=(4x-22) + (10x-4) +(x+11)
Since you can't simplify more take off the parentheses.
180=4x-22+10x-4+x+11
Simplify and/or combine like terms.
180=15x-15
Solve for x.
x=13
Then plug in 13 for x for angle QPR.
angle QPR=10(13)-4
Simplify.
angle QPR =126
