(a)
To find: The side opposite to
(a)
Answer to Problem 92E
The side opposite to the angle
Explanation of Solution
Given Information:
The given triangle is as follows.
Figure (1)
Calculation:
The side opposite to the right angle is called hypotenuse. It is the largest side of a right-angled triangle.
In the given triangle, the side opposite to the angle
Therefore, the side opposite to the angle
(b)
To find:The side adjacent to
(b)
Answer to Problem 92E
