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

-n+(-4)-(-4n)+6<br><br><br> solve
tigry1 [53]

Answer:

3n + 2

Step-by-step explanation:

-n+(-4)-(-4n)+6

= -n -4 +4n +6        [positive plus negative =  negative; ∴  +(-4) = -4

=4n - n +6 - 4                      negative plus negative = positive; ∴ -(-4n) = 4]

now subtract n from 4n and subtract 4 from 6

=3n + 2
