PLEASE PLEASE PLEASE ANSWER THESE ASAP 1. If a 40 foot tall ladder is placed 15 feet from the base of a house, how high up the house will the ladder reach?

2. Starting from the same spot in the woods, Presley ran 24 meters North to camp while her sister Ava ran 16 meters west. From this point, how far will Ava need to travel to reach camp​

Hope this helps! If I could have brainliest I'm trying to rank up :)

Step-by-step explanation:

1.x = 37.08 feet

Using the Pythagorean Theorem:

x^2 + 15^2 = 40^2

x^2 + 225 = 1600

x^2 = 1600 - 225

x^2 = 1375

x = SQRT(1375)

x = 5SQRT(55)

x = 37.08 feet

2.Using pathagorean it’s 16^2 + 24^2 = c^2

256 + 576 = 832

The answer is the sqrrt of 832

Which is 8sqrrt13 or 28.44

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
