Question

What’s the answer and give an explanation.

Answer 1

Answer:

14 = x and 2.5 = y

Step-by-step explanation:

For ABCD - the top is 8 and the sides are 11. 11 minus 8 is 3. 11 plus 3 equals 14, that’s x.

For GHIJ - the bottom is 8 and both sides are 5.5. So 8 minus 5.5 is 2.5. That’s y.

Answer 2

Q10/ scale factor of polygon ABCD to polygon GHIJ = 11/5.5 = 2

Q11/ scale factor of polygon GHIJ to polygon ABCD = 1:2

Q12/ x = 8 × 2 = 16

        y = 8 / 2 = 4

Q13/ ABCD ⇒ label x as 16, y as 4

         GHIJ ⇒ label HI line to 5.5

Q14/ ratio = 46 : 23

                = 2 : 1

hope this helps....
