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

B = - 40

Step-by-step 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
