Michael is building two ziplines out of metal cable so that he and his friends can ride them. The first zipline is 25 feet off the ground and the second is directly above it 43 feet off the ground. Both ziplines end on the same platform and have angles of depression 29° and 35°. How much more cable will the taller zipline need compared to the lower zipline?​

22 dimes and 9 nickels

step-by-step explanation:

the 3rd on is correct

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
