The sum of the other angles is 90°
Step-by-step explanation:
Given that triangle QRS is a triangle right angled at R
we have to determine the sum of the other two angles in the triangle QRS.
According to the angle sum property of triangle, the sum of all three angles in a triangles is equal to 180°.
<r=90°
<R+<Q+<S=180°
90+<Q+<S=180°
<Q+<S=180°-90°=90°
The sum of the other angles is 90°
