Answer:
<h2>
cosecθ = 1/sinθ = 11/6√2</h2>
Step-by-step explanation:
Given that cos θ =7/11, cosec θ = 1/sinθ in trigonometry.
Based on SOH, CAH, TOA;
cosθ = adjacent/hypotenuse = 7/11
adjacent = 7 and hyp = 11
Since sinθ = opp/hyp, we need to get the opposite to be able to calculate sinθ.
Using pythagoras theorem to get the opposite;
sinθ = 6√2/11
cosecθ = 1/sinθ = 1/( 6√2/11)
cosecθ = 1/sinθ = 11/6√2
Note the error; cscθ
1/cosθ but cscθ = 1/sinθ

Answer:
see explanation
Step-by-step explanation:
∠c = ∠ a = 47° ( vertical angles )
∠c and ∠b form a straight angle and are supplementary, thus
∠c + ∠b = 180, that is
47 + ∠b = 180 ( subtract 47 from both sides )
∠b = 133°
∠d = ∠b = 133° ( vertical angles )
That is a = c = 47° and b = d = 133°
The sum of the 4 angles = 133° + 47° + 47° + 133° = 360°
360° is the sum of the angles round a point , hence answer is correct
