I think it's D. A=1/2bh. So you get 12=1/2(1/2)h, or 12=1/4h. Then multiply to get h=48m

(cot theta + cosec theta)/(cosec theta (1 + (cot theta/ cosec theta)).

The given expression $\dfrac{\frac{cos \theta}{sin \theta} + \frac{1}{sin\theta} }{\frac{1}{sin \theta} (1+cos \theta)} =1$ is true

<h3>Proving trigonometry identity</h3>

Given the expression

$\frac{cot \theta + cosec \theta}{cosec \theta(1+\frac{cot \theta}{cosec \theta} )} =1$

Note that:

cotθ = cosθ/sinθ
cosecθ = 1/sinθ

Substituting the given parameters into the formula;

$\frac{\frac{cos \theta}{sin \theta} + \frac{1}{sin\theta} }{\frac{1}{sin \theta} (1+cos \theta)} =1$

Find the LCM of both the numerator and denominator

$= \dfrac{\frac{cos \theta + 1}{sin \theta} }{(\frac{1+cos \theta}{sin \theta} )}\\$

Divide the result to have:

$= \frac{1+cos \theta}{sin \theta} \times \frac{sin \theta}{1+cos \theta}\\ = \frac{1}{1}\\ = 1 (Proved)$
