Question

If A x tan (theta + 150) = B x tan (theta - 60)


​

Answer 1

Answer:

A×tan(θ+150∘)=B×tan(θ−60∘)

A

B

=

tan(θ−60∘)

tan(θ+150∘)

Put θ=90∘

A

B

=

tan(90∘−60∘)

tan(90∘+150∘)

=

tan30∘

tan(180∘+60∘)

=

tan30∘

tan60∘

A

B

=

then

A+B

A−B

=−

4

2

A+B

A−B

=−2

=

A−B

A+B

=−
