Question

Solve for x in the triangle. Round your answer to the nearest tenth.

20
X
52°
X =

Answer 1

25.4

Explanation:

use sine rule
`(a)/(sinA)`=
`(b)/(sinB)`

`(20)/(sin(52))` ×sin(90)

or

use sine rule
`(opposite)/(hypotenuse)` = sinФ

`(20)/(h)`=sin(52)

rearrange-

20÷sin(52)=h

(h is x)
