Question

How do you solve `SinA/14=sin104^o/25`?

Answer 1

`A=32.9^o`

Explanation:

In `sinA/14=sin104^o/25`

as `sin104^o=0.9703` - using tables or scientific calculator, however note that `sin104^o=sin(180^o-76^o)=sin76^o`

we have `sinA/14=0.9703/25`

and `sinA=14xx0.9703/25=0.5437`

and again using tables or scientific calculator

`A=32.9^o`
