Two hot air balloons are traveling along the same path away from a town,
horsena [70]

Answer:

it si this

Step-by-step explanation:

Simplifying

4y + -10 = 5 + -1y

Reorder the terms:

-10 + 4y = 5 + -1y

Solving

-10 + 4y = 5 + -1y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add 'y' to each side of the equation.

-10 + 4y + y = 5 + -1y + y

Combine like terms: 4y + y = 5y

-10 + 5y = 5 + -1y + y

Combine like terms: -1y + y = 0

-10 + 5y = 5 + 0

-10 + 5y = 5

Add '10' to each side of the equation.

-10 + 10 + 5y = 5 + 10

Combine like terms: -10 + 10 = 0

0 + 5y = 5 + 10

5y = 5 + 10

Combine like terms: 5 + 10 = 15

5y = 15

Divide each side by '5'.

y = 3

Simplifying

y = 3

First, you need to figure out whether you need to use sin, cosine or tan.
Since we know that we need to find the adjacent side of the triangle and also since we already know the opposite side of the triangle from the angle, we can use tan.
tan(20)=opposite/adjacent
tan(20)=(146.5)/adjacent
adjacent=(146.5)/tan(20)

403 meters away form the pyramid
