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.
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.
You're welcome, and bye. :)
The answer is 30.8
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

Yes, you are correct! You have correctly set up the proportion:
14/10 = x/22
To solve for x, you cross multiply:
10 * x = 14 * 22
Now, you can simplify the equation:
10x = 308
To isolate x, divide both sides of the equation by 10:
10x/10 = 308/10
x = 30.8
Therefore, the length of side x for Triangle 2 is indeed 30.8 cm. Well done!
Thank you
P.S ok bye:-) LOL
