Question

in a right angle triangle is one acute angle is double the other then write the relation between hypotenuse and small side

Answer 1

In ΔABC, if ∠B = 90, then sum of other two angles ∠A + ∠C = 90,
One angle is double the other :  let ∠A = 2∠C
then ∠A = 60, ∠B = 90, ∠C=30
Cos(30) = $\frac{a}{b}$, Sin(30) = $\frac{c}{b}$
Cos(60) = $\frac{c}{b}$, Sin(30) = $\frac{a}{b}$
