Question

Find the length of the lamppost to the nearest inch.

Answer 1

Answer:

109 inch

Step-by-step explanation:

we know that

$tan\theta=\frac{Perp}{Base} \\\theta=70\\Base=40 in$

So,

$tan(70)=\frac{Perp}{40} \\\\2.747=\frac{Perp}{40} \\\\2.747\times40=Perp\\\\Perp=109\quad in$

So, length of lamppost is 109 inch
