Answer:
the corresponding measurement of the original figure. A scale factor is a number used as a multiplier in scaling. (Units are not mentioned in a scale factor.) Example: A sidewalk 20 feet long is drawn on a map as 4 inches in length.

Answer:
20°
Step-by-step explanation:
The sum of all triangles must equal 180 degrees.
The measure of two angles of a triangle are each four times the measure of the third angle.
2x+x/4=180
The equation above illustrates a way to solve for X which represents the the independent angle measurement from the two angles.
x = 80
Above, we solved for x by simplifying both sides of the equation and then isolating x. So hmm...does 80 make sense?
80 / 4 = 20. So it is four times the measure of the 3rd angle. But does it all equal to 180?
2 * 80 + 20 = 180.
The angle of the third angle is 20 degrees.
5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 =
=(2.4495 - 1.4142): 4 = 0.258825
