It’s either b or d give me a moment to get the positive answer
Answer:
Other Side (B) = 9.45 inches
Step-by-step explanation:
Given:
Hypotenuse = 10 inches
Other Side (A) = 3.25 inches
Find:
Other Side (B) = ?
Computation:
According to Pythagoras theorem:

Other Side (B) = 9.45 inches
Answer: -34
Step-by-step explanation:
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
