Given this is a right triangle
85^2 = 7225
84^2 = 7056
85^2 - 84^2 = 169 = 13^2
Sin QR / QP = sin 84 / 85 = 81.2 deg

Answer:
Evaluate the left-hand side expression at the given value to get a number.
Evaluate the right-hand side expression at the given value to get a number.
See if the numbers match.
Step-by-step explanation:

Let's solve for x and z ~

[ they form co - exterior angle pair ]


now, it's time for x :
First angle z is equal to its vertical opposite angle, and then that angle forms co - interior angle pair with (3x - 28)
