4.a

5.c

6.b

Explanation:

Answer 2

D

Explanation:

Using the sine ratio in the right triangle

noting that sin45° =
`(1)/(√(2) )` ← exact value

sin45° =
`(opposite)/(hypotenuse)` =
`(8)/(h)`

Multiply both sides by h, then

h ×
`(1)/(√(2) )` = 8

Multiply both sides by
`√(2)`

h = 8
`√(2)` → D
