In ΔPQR Measure of angle Q at is 90°. If sinP = $$\frac{{12}}{{13}}$$ and PQ = 1 cm. Then what is the value of cotR =?
A. 2.4
B. 2.6
C. 3
D. 4
Answer: Option A
Solution (By Examveda Team)
$$\eqalign{ & 5{\text{ unit}} \to 1\,{\text{cm}} \cr & {\text{1 unit}} \to \frac{1}{5}\,{\text{cm}} \cr & \cot R = \frac{{2.4}}{1} = 2.4\,{\text{cm}} \cr} $$
