Question

13) help pls I have the answers the only thing I need is to show the work.

Which is the best strategy to use for finding the length of the missing side?

Answer: D

Answer 1

D

Explanation:

Pythagorean Theorem equation:

`a^(2) + b^(2) = c^(2)`

a and b are the sides and c is the hypothenuse

`a^(2) + b^(2) = c^(2)`

`15^(2) + 5^(2) = c^(2)`

225 + 25 =
`c^(2)`

250 =
`c^(2)`

√250 = √
`c^(2)`

15.8 = c

Answer 2

Pythagorean Theorem :))

c=
`a^(2)+b^(2)`

c=
`√(5^2+15^2)`

c=
`5√(10)`

c≈15.81
