Atree forms a right angle with the ground. if you place the base of a 12-foot ladder 3ft from the tree, how high up the tree will it reach?

12.37ft

Step-by-step explanation:

The formula to find the missing side of a triangle is a^2 + b^2 = c^2

so all you have to do is put 3 and 12

3^2 + 12^2 = c^2

9 + 144 = c^2

153 = c^2

√153 = 12.37

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
