Question

The side lengths of a 45-45-90 triangle are in the ratio 1:1:√2. What is sin 45°?

Answer 1

`(√(2) )/(2)`

Explanation:

To find the value of sin 45° we divide the opposite side length with hypotenuse

`(1)/(√(2) )` we then multiply this by
`√(2)` because denominator cannot be irrational

`(1)/(√(2) )` x
`√(2)` =
`(√(2) )/(2)` gg
