PLZ HELP I DONT UNDERSTAND AND I NEED IT DONEE ILL GIVE BRAINLIEST Max observes the zoo and the library from a helicopter flying at a height of 300 times square root of 3 feet above the ground, as shown below:

A helicopter is flying at a height of 300 multiplied by square root of 3 feet above the ground. A zoo and a library are on the ground on the same side of the helicopter. The angle made by the line joining the helicopter and the zoo with the ground is 60 degrees. The angle made by the line joining the helicopter and the library with the ground is 30 degrees.

What is the distance between the zoo and the library?

300 feet
600 feet
900 feet
1,200 feet

so, converting firstly the mixed fractions to improper fractions and then "adding".

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
