triangle qrs is a right triangle with the right angle at vertex r. the sum of m∠q and m∠s must be equal to 45°. greater than 45° and less than 90°. equal to 90°. greater than 90° and less than 180°.

triangle qrs is a right triangle with the right angle at vertex r. the sum of m∠q and m∠s must be equal to 45°. greater than 45° and less than 90°. equal to 90°. greater than 90° and less than 180°.

Answer

Explanation:

Step1: Record el teorema de ángulos internos

La suma de los ángulos internos de un triángulo es 180°. $$m\angle Q + m\angle R+ m\angle S=180°$$

Step2: Sustituye el valor del ángulo recto

Como $\angle R = 90°$, entonces $m\angle Q + 90°+ m\angle S=180°$.

Step3: Resuelve para $m\angle Q + m\angle S$

Restando 90° de ambos lados de la ecuación: $m\angle Q + m\angle S=180° - 90°=90°$.

Answer:

C. equal to 90°.
