Question

If angle 1 equals x squared and angle 2 equals 90-x what is measurement of angle PQR

Answer 1

We know that all angles added together equal to 180.
Let y represent the missing angle

Angle 1: x^2
Angle 2: 90-x

x^2+(90-x)+(y)=180
y=180-x^2-90+x
y=-x^2+x+90
y=(x+9)(x-10)

Therefore, y could be 10 (because -9 is not an existant/possible solution since it is negative)

Hope I helped :)
