Question

I need to know how to do it aswell

Answer 1

x = 5

Explanation:

The small triangle has been dilated by 2 making it twice as big as before.

The side that measures 10 would be dilated by 0.5 to find x which is half a big.

10 x 0.5 = 5

Now check your work. On one side it asks 6x. So, 6 x 5 = 30. Since 30 is twice as much as 15. The rule applies that x = 5.

5 x 2 = 10

6 x 5 = 30

15 x 2 = 30

Answer 2

x= 3

Explanation:

x on triangle 1 is 5 times less than 15

x on triangle 2 is 3 times bigger than 10

Hope this helps!
