Question

What is the dilation

Answer 1

Answer:

We say height = 1.25

1:25+1:6 divided by 2 = 1:5 average scale factor

You state;

1.25 scale factor upwards

1.60 scale factor sideways

= Average 1:5

Step-by-step explanation:

New by old for scale factor

Shows enlargement see if this is less than 1.

15/12 = 1.25

8/5 = 1.6

These numbers will show  what you multiply by to increase the size.

The side is 1.25

The base is 1.60

The hypotenuse is 1.70

you see the ratio is 1.25:1.60:1.70 = 1.50 average

To find the hypotenuse

(s) 12 x 12 = 144                                 (s) 15 x 15 = 225

(b): 5 x 5 = 25                                    (b) 8 x 8 =  64

(h): 144+25 = 169 slope                     (h)  225+64 = 289 slope

289/169 = 1.70 =  70% increase.

7+2.5+6 = 15.5 = 1.5 average increase.
