In ΔPQR measure of angle Q is 90°. If tanP = 4/3 and PQ = 1.5 cm. Then what is the length (in cm) of side PR?

Answer: Option B

Solution

Answer: Option B

Solution:

$$\begin{array}{rl}& \tan \text{P}=\frac{4}{3}\\ & 3\text{ unit}\to 1.5\text{ cm}\\ & 1\text{ unit}\to \frac{1.5}{3}\text{ cm}=.5\text{ cm}\\ & \text{PR}=2.5\text{cm}\end{array}$$
