Question

find the width of a rectangle if the diagonal is 18, and the length is 8

Answer 1

think of the diagonal separating the rectangle into right triangles. you have the hypotenuse (diagonal) and a leg (the length)

to find the with use pythagoreon theorem

8^2+b^2=18^2

solve for b

Answer 2

would be equal b=388

Answer 3

don't forget to un square root it

Answer 4

may i get an example how to do this work ?

Answer 5

64+b^2=324
b^2=260
b= sqrt{260}

Answer 6

how you get 260 on the example did u divide something

Answer 7

wait if u subtract that wouldnt u get -260

Answer 8

324-64=260

Answer 9

thank u caleb
