Question

We are given a triangle ABC with hypotenuse AC = 10 cm and one of its sides AB = 6 cm. What will be the angle opposite the hypotenuse AC and what will be the measure of that angle?

• A. $\angle B,{90}^{\circ }$
• B. $\angle A,{60}^{\circ }$
• C. $\angle C,{90}^{\circ }$
• D. $\angle B,{60}^{\circ }$

Answer 1

The correct option is A $\angle B,{90}^{\circ }$

The angle opposite to the hypotenuse is always a right angle. So, its measure is ${90}^{\circ }$.
Since the hypotenuse is AC here, the angle opposite to that is $\angle B$
So, $\angle B={90}^{\circ }$.
