I believe its asking to find X, Im sorry if Im wrong and its something else, the question confuses me.

1) x = 16

2) x = 16

3) x = 16

X always equals 16

____________________________
EXPLANATION

x/2 - 5 = 3

16/2 - 5 = 3

8 - 5 = 3

3= 3

x/2 = 8

16/2 = 8

8 = 8

x = 16

16 = 16

Marking me brainliest would be much appreciated! Im trying to get on the leaderboard

m_a_m_a [10]

Answer:

-8/3

Step-by-step explanation:

To solve for x-intercept, we set y as 0.

0 = 3x + 8

-8 = 3x

-8/3 = x

The x-intercept of the line is -8/3.

A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground. How high is the top o

DochEvi [55]

Answer:

The height of tree house is 70.71 feet

Step-by-step explanation:

We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground

Refer the attached figure

Length of rope AC = Hypotenuse =100 feet

The top of a tree house to the ground forms a 45∘ angle of elevation from the ground = $\angle ACB = 45^{\circ}$

We are supposed to find the height of tree house i.e.AB = Perpendicular

So, Using trigonometric ratio

$Sin \theta = \frac{perpendicular}{Hypotenuse}\\Sin 45= \frac{AB}{AC}\\\frac{1}{\sqrt{2}}=\frac{AB}{100}\\100 \times \frac{1}{\sqrt{2}}=AB\\70.71=AB$

Hence The height of tree house is 70.71 feet
