Question

I need help asap!!!!!

Answer 1

h²=p²+b²

(19)²-(9)²=b²

361-81= b²

b²=280

b= √280

:. b=+-16.733

Answer 2

16.7

Explanation:

We can use the Pythagorean Theorem
`a^(2)` +
`b^(2)` =
`c^(2)`. So we write the equation below and solve for b.

`9^(2)` +
`b^(2)` =
`19^(2)`

81 +
`b^(2)` = 361

`b^(2)` = 280

b = 16.7
