1. 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 $$ riangle$$ XYZ, => $$tan(X)=frac{YZ}{XY}$$ => $$frac{15}{8}=frac{YZ}{16}$$ => $$YZ=frac{15}{8} imes16=30$$ cm => Ans - (B)
