Question

Which equation could be used to find the height of the flagpole?

Answer 1

Given a fragpole which makes a right angle with the point of observation with the angle of elevation as 50°.

Let x be the height of the flagpole, then

$\sin50^o= \frac{x}{5}$

Therefore, the equation that could be used to find the height of the flagpole is
x/5 = sin 50
