Use a proportion to find the length of side x for the pair of smilar figures below.

They're both right triangles.
Triangle 1 has 14cm on the the right side and 10cm on the bottom.
Triangle 2 has x on the right side and 22cm on the bottom.
My answer
14/10=x/22
10*x=14*22
10x/10=308/10
X=30.8
Am I right?
Thank you.

  1. Yes, 30.8 is the value of x. I also double-checked by plugging 30.8 into the right side as well.

    14/10 = 1.4

    30.8/22 = 1.4.

    Therefore, because both sides equal 1.4 when you solve with 30.8 plugged in, it must be correct.

    I hope this helps! :)

    P.S. I will help you some more tomorrow.

  8. btw this is correct- another way if we didnt need to use proportions could be doing 10/22 = 2.2 then we multiply 2.2 x 14 which equals 30.8
