Johnny's town is having an old-fashioned circus under a large tent. In order to keep the tent from falling down, workers must ti

Zepler [3.9K]

Answer: 62 feet approximately.

Step-by-step explanation:

1. Based on the information given in the problem, you can draw a right triangle as the one shown in the image attached, where the height of the tent is represented with $x$ . Therefore, you can calculate it as following:

$sin\alpha=\frac{oppostite}{hypotenuse}$

Where:

$\alpha=62\°\\opposite=x\\hypotenuse=70$

2. Substitute values and solve for $x$ , then the height of the circus tent is:

$sin(62\°)=\frac{x}{70}\\x=70*sin(62\°)$

$x=61.81$ ≈ $62ft$

Determine if DE is parallel to AC. Show all your work!!!

skelet666 [1.2K]

Answer:

Step-by-step explanation:

We will prove the converse of the postulate,

"If a line parallel to one side of a triangle and it intersects other two sides of the triangle, then the line will divide both the sides in the same ratio"

Segment DE intersects AB and BC at D and E respectively,

Ratio of the segments of two sides,

$\frac{AD}{DB}=\frac{CE}{EB}$

$\frac{22.5}{15}=\frac{24}{40-24}$

1.5 = 1.5

True.

Therefore, lines AC and DE are parallel.
