3. A ladder is placed 5ft away from a building. The ladder comes up to 12 ft on the side of the
irina [24]

Answer:

13 feet long

Step-by-step explanation:

This situation forms a right triangle, where the ladder is the hypotenuse, the distance away from the building is the short leg, and the height to the side of the building is the long leg.

Use the pythagorean theorem, and solve for c, the hypotenuse:

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

13 = c

So, the ladder is 13 feet long

How do you solve -3+r/3=-5
MAVERICK [17]

Answer:

r=-6

-9+r=-15

2) Add 9 to both sides:

r=-6

Footnotes:

1) In step 1 when I multiplied both sides of the equation by 3, don't forget you also have to multiply -3 by 3 because it is not part of the fraction (which is how I got -9)
