Question

I want to know if my answer to these questions were right

Answer 1

From the triangle given,

a) To find cosθ,

`\cos \theta=(Adj)/(Hyp)=(a)/(b)`

b) To find tanτ,

`\tan \tau=(Opp)/(Adj)=(a)/(x+y)`

c) To find tan (θ+φ),

`\tan (\theta+\Phi)=(Opp)/(Adj)=(x+y)/(a)`

d) To find sin μ,

`\sin \mu=(Opp)/(Hyp)=(a)/(b)`

e) To find csc τ,

`\csc \tau=(1)/(\sin \tau)=(1)/((a)/(c))=(c)/(a)`

f) To find sec (θ+φ),

`\sec (\theta+\Phi)=(1)/(\cos (\theta+\Phi))=(1)/((a)/(c))=(c)/(a)`

Answers given above.
