Question

HELP!!!

the length of one of the sides of a triangle is 8. what is the hypotenuse?
8
8√2
4√2
√8

Answer 1

B. 8√2

Explanation:

I just did this question and this was the right answer for me, sorry that I answered this late.

Answer 2

AT = 8
`√(2)`

Explanation:

Using the sine ratio in the right triangle

and sin45° =
`(1)/(√(2) )`

sin45° =
`(opposite)/(hypotenuse)` =
`(AB)/(AT)` =
`(8)/(AT)`

Multiply both sides by AT

AT × sin45° = 8, that is

AT ×
`(1)/(√(2) )` = 8

Multiply both sides by
`√(2)`

AT = 8
`√(2)`
