Question

1.

If sin(-A) = tan 335,3 : A € (-180; 180) then the size of Ais?

Answer 1

Answer: 27.38

Explanation:

Firstly let start finding:

tan 335.3°

Which is -0.4599

Then

sin(-A) = tan 335.3

sin(-A) = -0.4599

-A= sin inverse of (-0.4599)

-A= -27.38

Divided both side by -

A= 27.38

Answer 2

`A=-6.746`

Explanation:

Given that

sin(-A)=tan353.3

A∈(-180, 180)

Required:

Size of A=?

solution:

using calculator we get,

`tan(353.3)=-0.117`

so
`sin(-A)=-0.117`

now
`A= Sin^(-1)(-0.117)`

`A=-6.746`
