Question 25

In ∆XYZ measure of angle Y is 90°. If tanX = 15/8, and XY = 16cm, then what is the length (in cm) of side YZ?

Solution

Given : XY = 16 cm and tanX = 15/8

To find : YZ = ?

Solution : In right $$\triangle$$ XYZ,

=> $$tan(X)=\frac{YZ}{XY}$$

=> $$\frac{15}{8}=\frac{YZ}{16}$$

=> $$YZ=\frac{15}{8}\times16=30$$ cm

=> Ans - (B)
