Answer:

Step-by-step explanation:

Given

$\frac{x}{\sqrt{2} }$

Multiply numerator/ denominator by $\sqrt{2}$ to rationalise the denominator

= $\frac{x\sqrt{2} }{\sqrt{2}(\sqrt{2}) }$

= $\frac{x\sqrt{2} }{2}$ → A

You are standing on a small fire tower 50 feet from a tree. You notice a squirrel in the tree. You measure the angle of depressi

irina [24]

Answer:

44.81 feet

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ACD

Find the length side AC (height of the small fire tower)

$tan(52^o)=\frac{AC}{50}$ ---> by TOA (opposite side divided by the adjacent side)

Solve for AC

$AC=tan(52^o){50}$

$AC=64\ ft$

step 2

In the right triangle ABE

Find the length side AB

$tan(21^o)=\frac{AB}{50}$ ---> by TOA (opposite side divided by the adjacent side)

solve for AB

$AB=tan(21^o){50}$

$AB=19.19\ ft$

step 3

How many feet off the ground is the squirrel?

Subtract the length side segment AB from the length side segment AC

$64-19.19=44.81\ ft$

What is the reciprocal of<br> of 1/5?

irga5000 [103]

The reciprocal of 1/5 is 5.

Reciprocals are numbers than when multiplied equal a product of 1. In this question, 1/5 * 5 = 1. An easy trick for finding reciprocals is flipping a fraction.

Hope this helps!!
