Answer:

The answer is option 2.

Step-by-step explanation:

First, you have to eliminate brackets, you have to divide -1.5 to both sides :

$- 1.5(4 - r) = - 12$

$- 1.5(4 - r) \div - 1.5= - 12 \div - 1.5$

$4 - r = 8$

Next you have to solve r :

$4 - r = 8$

$- r = 8 - 4$

$- r = 4$

$r = - 4$

From the diagram below, if the tree is 34 ft. tall, and the angle of elevation from point B to the top of the tree is 26 °, find

lana66690 [7]

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.

<h3>What is the distance between the tree and point B?</h3>

Given the data in the question;

Height of tree opposite angle of elevation = 34ft
Angle of elevation θ = 26°
Distance between tree and point B| Adjacent = ?

Since the scenario form a right angle triangle, we use trig ratio.

tanθ = Opposite / Adjacent

tan( 26° ) = 34ft / x

We solve for x
x = 34ft / tan( 26° )

x = 34ft / 0.4877

x = 70ft

Given the height of the tree and the angle of elevation from point B, the distance between the tree is from point B is approximately 70ft.
