Question

Please help !! Use Pythagorean theorem :) and show your work if you can thanks :”) will give b

Answer 1

Answer:

$b=\sqrt{1575}$ ≈ 39.7ft

Step-by-step explanation:

The Pythagorean theorem:

$a^{2}+ b^{2}= c^{2}$

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)

First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.

$45^{2}+ b^{2}= 60^{2}$

$2025+b^{2} =3600$

To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

$b^{2} =1575$

$b=\sqrt{1575}$ ≈ 39.7ft
