A roofer leaned a 16-foot ladder against a house. If the base of the ladder is 5 feet from the house, how high up the house does

elixir [45]

Answer:

15.20feet

Step-by-step explanation:

Length of the ladder = 16foot (hypotenuse)

BAse of the ladder from the house = 5feet (adjacent)

height of the house = x (opposite)

Using the pythagoras theorem

hyp^2 = opp^2 + adj^2

16^2 = 5^2 + opp^2

256 = 25 + opp^2

opp^2 = 256-25

opp^2 = 231

opp =√231

opp = 15.20

Hence the house is 15.20feet high up the house

beks73 [17]

Answer:

Step-by-step explanation:

If you want to find the least amount of packages, you'll have to find what multiple they have in common.

One way to find this is 6x8, which is 48, but that isn't always the lowest.

Here are the first few multiples of six: 6, 12, 18, (24), 30, 36, 42, and 48.

What is the value of x?<br> 20<br> 35<br> 60<br> 70

Evgen [1.6K]

They are vertical angles, and so set them equal to each other

x + 40 = 3x

Isolate the x. Subtract x from both sides

x (-x) + 40 = 3x (-x)

Simplify

40 = 3x - x

40 = 2x

Isolate the x. Divide 2 from both sides

40/2 = 2x/2

x = 40/2

x = 20

20, or (A) is your answer

hope this helps
