Question

I need help with number 2 ASAP!!!!! The pictures is number 2.

Answer 1

`a=22.5\ units`

Explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

so

In this problem

If polygon RSUPE is similar to polygon KQUIC

then

`(RS)/(KQ)=(RE)/(KC)`

substitutes the values and solve for a

`(a+2)/(14)=(17.5)/(10)\\ \\10a+20=14*17.5\\ \\10a=245-20\\ \\a=225/10\\ \\a=22.5\ units`
