Height of a pole is 8cm. Find the length of the rope tied with it's top from a point on the ground at a distance of 6m from it's bottom

The answer is 10m

Step-by-step explanation:

a^2 + b^2 = c^2

a = 8

b = 6

Step-by-step explanation:

64-36=28

Root28=2root7

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

is there a question here?
