2x - 2 = x + 2
2x - x = 2 + 2 = 4
x = 4
5y - 8 = y + 24
5y - y = 24 + 8
4y = 32
y = 8.
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

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