Question

if the right angle triangle one acute angle is 30 .find the other acute angle of a triangle​

Answer 1

$\huge \purple A \purple N \purple s \purple W \purple e \purple \R :-$

ABC is a triangle

Right angled at B

So ,

Angle A = ?

Angle B = 90°

Angle C = 30°

Sum of all the angles of the triangle are equal .

So ,

A + B + C = 180°

A + 90° + 30° = 180°

A + 120° = 180°

A = 180° - 120°

A = 60°

Hence , the other acute angle , that is the third angle is 60°
