Answer:

C. (2, 1)

Step-by-step explanation:

-3y = x-5

x+ 5y = 7

Subtract x from both sides in the first equation. Write the second equation below it.

-x - 3y = -5

x + 5y = 7

Add the two equations above.

2y = 2

Divide both sides by 2.

y = 1

Substitute y with 1 in the second original equation and solve for x.

x + 5(1) = 7

x + 5 = 7

Subtract 5 from both sides.

x = 2

{-x - 3y = -5

{x + 5y = 7

____________

2y = 2

__ _

2 2

y = 1 [Plug this back into both equations to get the x-coordinate of 2]; 2 = x

JulsSmile [24]

The length of ladder is 30 ft.

<h3>How can the feet that made up the side of the building is the top of the ladder be known ?</h3>

The formula below can be used in solving the problem

Tan (∅)= \frac{opposite}{adajacent}

∅=70°

opposite = BC

Adjacent  = 12 ft

70°= opposite/ 12

opposite= 32.96 ft

Therefore, The length of ladder is 30 ft.

NOTE; Since the actual diagram can not be found i solved another on on the same topic
