Question

In right angled triangle the acute are in the ratio4:1 the acute angles are

Answer 1

$let \: \: acute \: \: angles \: \: are \: \: 4x \: \: and \: \: x \\ according \: \: to \: \: question \\ = > 4x + x = 90 \\ = > 5x = 90 \\ = > x = \frac{90}{5} \\ = > x = 18 \\ \\ now \: \: 4x = 4 \times 18 = 72 \\ \\ so \: \: acute \: \: angles \: \: are \: \: 72 \: \: and \: \: 18$
