Question

Find the side length, b.
Round to the nearest tenth.
B=90°
a=6
c=7

Answer 1

Yes, B is equal to 9.2

Answer 2

b = 9.2

Explanation:

Using the Pythagorean theorem (in your case):
`a^(2) +c^(2) = b^(2)`

Plug in your values and solve for x:

`6^(2)+7^(2) =b^(2)\\36+49 =b^(2) \\85 = b^(2) \\b = √(85) \\b = 9.2`
