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?
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)
