Question

Find the value of X around the lengths of the nearest unit

Answer 1

Answer: 35 ft

Explanation:

Given

Vertical height from the eyes of the person to the top of the flag is
`X-5`

Horizontal distance is
`30\ ft`

The angle of elevation is
`45^(\circ)`

From the figure, we can write

`\Rightarrow \tan 45^(\circ)=(X-5)/(30)\\\Rightarrow 1=(X-5)/(30)\\\\\Rightarrow X-5=30\\\\\Rightarrow X=35\ ft`
