Question

A triangle has sides A, B, and C. The angle between sides A and B is `(pi)/2`. If side C has a length of `25` and the angle between sides B and C is `pi/12`, what is the length of side A?

Answer 1

Length of side A = 6.4705

Explanation:

`C/sinC=A/sinA`
Given side `C=25` , `/_C=(pi/2)` & `/_A=(pi/12)`
`:.25/sin(pi/2)=A/sin(pi/12)`
`A=(25*sin(pi/12))/sin(pi//2)`
`A=(25*sin(pi/12))/1=25*0.2588=` 6.4705
