Question

I need someone to work out this question for me, I already know the answer; I just need to know how to do this.

Answer 1

The polygons are similar, but not necessarily drawn to scale. Find the value of x.

ANSWER: x = 9, y = 27

Answer 2

when the polygons are similar, their sides are proportional.

Answer 3

so, (x-1)/6 = 16/12
you get x from here.

Answer 4

(y+1) /21 = 16/12
you get y from here.

Answer 5

Ahh, okay. That makes sense! Thank you so, so much.

Answer 6
