Tim looks up at the top of a tree at an angle of elevation of 40 degrees. If heis 5 ft tall and 10 ft from the tree, how tall is

dolphi86 [110]

<h2>Answer:</h2>

13.391 ft

<h2>Explanations:</h2>

The schematic diagram of the given question is shown below;

The height of the tree is expressed as:

H = h +5

Determine the value of h using the SOH CAH TOA identity

$\begin{gathered} tan\theta=\frac{opposite}{adjacent} \\ tan40^0=\frac{h}{10} \\ h=10tan40 \\ h=10(0.8391) \\ h=8.391ft \\ \end{gathered}$

Determine the height of the tree

$\begin{gathered} H=h+5 \\ H=8.391+5 \\ H=13.391ft \end{gathered}$

Hence the height of the tree is 13.391ft

50 points and BRAINLIEST<br><br> .15m - .13m = 69.96 - 55.96

weeeeeb [17]

Answer:

m=7

Step-by-step explanation:

15m−13m=69.96−55.96

Step 1: Simplify both sides of the equation.

15m−13m=69.96−55.96

15m+−13m=69.96+−55.96

(15m+−13m)=(69.96+−55.96)(Combine Like Terms)

2m=14

2m=14

Step 2: Divide both sides by 2.

2m

2

=

HELP ASAP! AGE PROBLEM!! WILL MARK BRAINLIEST!!!

Gennadij [26K]

Answer:

<u>The present age of the mother is 30 years old</u>

Step-by-step explanation:

Age of Jane = x

Age of Billy = 5x (Billy is five times as old as Jane)

Age of Sara = 15x (Their mother is now three times as old as Billy)

In 2 years Sara will be eight times as old as Jane, therefore:

15x + 2 = 8 (x + 2)

15x + 2 = 8x + 16

15x - 8x = 16 - 2

7x = 14

x = 14/7

x = 2 ⇒ 5x = 10x ⇒ 15x = 30

Jane's present age is 2, Billy's present age is 10 and Sara's present age is 30

<u>The present age of the mother is 30 years old</u>
