Question

Can I get the answer for those

Answer 1

1) 5.64

2) 17.321

1)
`(21)/(28)`

2)
`(16)/(34)`

3)
`(28)/(35)`

4)
`(32)/(24)`

Explanation:

SOH - CAH - TOA

Sin =
`(O)/(H)` Cos =
`(A)/(H)` Tan =
`(O)/(A)`

O = opposite, A = adjacent, H = hypotenuse

First two, use Pythagorean Theorem

If you want to calculate the angle on the last 4, use inverse of function and put in the ratio.

For example :

1) Tan Z =
`(21)/(28)`

`Tan^(-1)` (
`(21)/(28)`)

Z = 36.9°
