Question

One of the acute angle of a right triangle is ${54}^{\circ }$, find the other acute angle.

Answer 1

Given one of the acute angles of a right angle triangle is ${54}^{\circ }$.
Let the unknow angle be $x^{\circ }$
As sum of three angles in a triangle$={180}^{\circ }$
$\Rightarrow x+90+54=180$
$=180-(90+54)={36}^{\circ }$

Therefore, the other acute angle $={36}^{\circ }$.
