Step-by-step explanation:
0.5 ( r + 2.75 ) = 3
r + 2.75 = 3 / 0.5
r + 2.75 = 6
r = 6 - 2.75
r = 3.25
Answer:
8.6
Step-by-step explanation:
You need to use the Patagorean theorem! :) Just do seven squared and five squared add them up and then square root them!!
Answer:The base of the ladder from the tree is 28ft
Step-by-step explanation:
Using pythagorean theorem
Let 100ft= hypothesis is the right angle triangle
Let 96ft be the height of the ladder
Let x be the base of the right angle triangle between the base of the ladder and the tree
h^2=a^2+b^2
100^2=96^2 +b^2
10,000=9216 +b^2
b^2=10,000-9216
b=sqrt(784)
b=28ft
4280 because 75+5+4200= 4280
