Tan PQS = 3/4
Angle PQS = inverse Tan (3/4)
Use calculator to find tan^-1(3/4)
=36.87
h = 5 (Pythagoras theorem)
Angle PQS = angle QSR (alt angle)
Tan QSR = QR / 5
QR = 3/4 x 5
= 3.75

Since angle PQS = angle QSR,
Tangent QSR = Tangent PQS = 3/4
The h in solution is QS = 5
Tangent QSR = Tangent PQS = 3/4
The h in solution is QS = 5
It was great
