Answer:
The scale factor should be 1:2 cause from 2.1 to 4.2 is doubled and so is 7.5 to 15 and 5.5 to 11.
Step-by-step explanation:

Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
Since the side which measures 10 is a vertical projection of the hipotenuse x on a 20 degree angle:
10 = x*sin(20°)
x = 29.238044
Since we have to round to the nearest hundreth:
x = 29.24 m
The segment was only rotated, not changed. It would be the same length as the original.
To find the length, use the distance formula.

(5, 8) would be point 1.
(-6,8) would be point 2.
Plug them into the formula.

Simplify.



Square root this answer.

Negative distances aren't possible, so your answer is 11.
