Question

What is the value of x?​

Answer 1

135????

Explanation:

Answer 2

x = 8

Explanation:

Using the sine ratio in the right triangle and the exact value

sin45° =
`(√(2) )/(2)`, then

sin45° =
`(opposite)/(hypotenuse)` =
`(4√(2) )/(x)`

Multiply both sides by x

x × sin45° = 4
`√(2)` ( divide both sides by sin45° )

x =
`(4√(2) )/((√(2) )/(2) )`

= 4
`√(2)` ×
`(2)/(√(2) )` = 4 × 2 = 8
