Step-by-step explanation:
We see a right triangle here.
Use the Pythagorean Theorem:
a^2+b^2=c^2
a & b=legs
c=hypotenuse
a^2+15^2=20^2
a^2+225=400
a^2=175
a=13.2287565553
a=13.2
The missing side is 13.2cm

1 : 36
Step-by-step explanation:
To obtain the scale factor, the dimensions must be in the same units.
Using the conversion
1 foot = 12 inches, then
