Answer:

$(a)\ h = d * \tan(\theta)$

$(b)\ h = 30.57m$

Step-by-step explanation:

Given

$\theta = 17^o$

$d =100m$

$h = ??$

See attachment for illustration

Solving (a): Trigonometry ratio to calculate h.

From the attachment, we have:

$\tan(\theta) = \frac{h}{d}$

Multiply both sides by d

$d * \tan(\theta) = \frac{h}{d} * d$

$d * \tan(\theta) = h$

Rewrite as:

$h = d * \tan(\theta)$

Solving (b): The value of h

We have:

$\theta = 17^o$

$d =100m$

So:

$h = 100m * \tan(17^o)$

$h = 100m * 0.3057$

$h = 30.57m$
