Question

The equation sin (25 degree) equals StartFraction 9 Over c EndFraction can be used to find the length of Line segment A B.

Answer 1

`AB = 21.3`

Explanation:

Given

`\sin(25) = (9)/(c)`

See attachment

Required

Find AB

We have:

`\sin(25) = (9)/(c)`

Make c the subject

`c = (9)/(\sin(25))`

`c = 21.3`

From the attached triangle;

`AB = c = 21.3`

Hence:

`AB = 21.3`
