Answer 1

$\huge \sf{Question:}$

The sum of two angles of a triangle are 90⁰, find the third angle.

$\huge\sf\purple{Answer :-}$

According to the theorem - Angle sum property

the sum of interior angles of a triangle is 180°

Let us consider : ∆ABC

∠A + ∠B + = 90° (given)

we know that :-

∠A + ∠B + ∠C = 180°

90° + ∠C = 180°

∠C = 180° - 90°

∠C = 90

Therefore the third angle = 90°
