Question

What is tan angle QTR if line PR is tangent to circle T at Q, and TS = 1 cm?

Answer 1

Tangent = opposite / adjacent

In the diagram:
TQ is the short leg or the opposite
QR is the long leg or the adjacent
TR is the hypotenuse. TS is part of the hypotenuse.

Tan(QTR) = TQ / QR

TS = 1 ; TQ = TS  so, TQ = 1

Tan(QTR) = 1/QR

I think the answer is C.RQ
