Answer 2

Answer:

θ + ∅ = π/4

Step-by-step explanation:

Given : tan θ = 5/6 and tan ∅ = 1/11.

We know that tan(A + B) = (tanA tanB)/(1 - tan A tanB)

⇒ tan(θ + ∅) = (tan θ + tan∅)/1 - tan θ tan ∅

                    = (5/6 + 1/11)/1 - (5/6)(1/11)

                    = (61/11)/(61/11)

                    = 1.

So, tan(θ + ∅) = 1

⇒ tan(θ + ∅) = tan 45°

⇒ θ + ∅ = π/4.

Hope it helps!
