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.
