Answer:
Follows are the solution to this question:
Step-by-step explanation:
In point A:
The two-point C and y is given, where C is the scale drawing lengths and y is the actual mural lengths so, the formed equation is:

In point C
:
Using the value of the scale:
let 1 feet: 20 feet
therefore the equation is:

The size of c will be the length of:

The diagram c scale width will be:

Answer: Option 4
Step-by-step explanation:
Similar triangles have congruent angles, so this means that the sines, cosines, and tangents should be the same.
Thus, the side lengths of the triangle we want to find should be multiples of
.
- This eliminates options (1) and (3).
Between options 2 and 4, we know that the Pythagorean theorem is not satisfied by option (2), thus we should eliminate it.
This leaves us with option (4)
.9 = 90% so .95 = 95% and .95 is bigger that .9
