Question

Finding side length of the 90-degree angle triangle

Answer 1

x = 4

Explanation:

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

sin45° =
`(1)/(√(2) )`

sin45° =
`(opposite)/(hypotenuse)` =
`(x)/(4√(2) )` =
`(1)/(√(2) )` ( cross- multiply )

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

x = 4
