Answer:

16.6 feets .

Step-by-step explanation:

Length of wire = 30 feets

Distance between base of tree and ground = 25 feets

Height of tree, h

Using Pythagoras rule :

h² = 30² - 25²

h² = 900 - 625

h² = 275

h = sqrt(275)

h = 16.583

h = 16.6 feets

Height of tree is 16.6 feets

Help plz ? Enter the slope of the line

Dmitrij [34]

(-2,4), (2,5)

Slope equation : (y₂-y₁) / (x₂-x₁)

Plug in the values.

m = slope

m = (5-4) / (2 + 2)

Simplify.

m = 1/4

So, your slope is 1/4
