Answer:

8.8

Step-by-step explanation:

if you use the sin, cos, and tan method. 20 is the h, x is the a and the blank side is the o. if you take way the side without the o you have the a and h which means you have cosine. If you did the equation as cos64=x/20 Then multiply both sides by 20 to get the X by it so you will have 20 COS 64 and once you want a play that together you have 8.8 equals X.

What is the solution set for [-x]=10
Lesechka [4]
X = -10

Because it is the "absolute value" of "10"

Here's why

-X - 10 = 0, right ?

So, now we have to add a positive 10 to each of our sides to get one step closer to our answer

-X + 10 = 0 ⬅️cancel this
0 + 10 = 10 ⬅️keep this

We can multiply by a negative 1 (-1 )

10(-1) = -10
0(-1) = -0

So that's how we found out that X = -10

A regulation soccer field has an area of 59,400 square feet. If the length is 330 feet, what is the width in feet
Juli2301 [7.4K]

Answer:

The answer is 180 feet.

Step-by-step explanation:

Here's your equation. (330 x W = 59,400).  If you want to find the width then divide 59,400 by 330 and you get 180 feet.

You can check by multiplying 330 and 180 which will result in 59,000.

So the correct answer is 180 feet.
