Question

In the right triangle above, a = 99 and c= 124. Find the value of b, rounded to the nearest tenth.

Answer 1

B= -40

Explanation:

So a right triangle has to = 180

So we write the given, which 124+99

we are trying to get 180 so lets subtract that by the equation, 180-124+99

180-(124+99)

12+99=223

180-223

=-43

But in your case it has to be rounded to the nearest tenth

So the answer is -40
