The measure of each angle of angle ABC is equal to the corresponding angle of angle A' B' C' when angle A' B' C' coincides with the other three triangles. The measures of the angles of the triangle are preserved as the figure rotates.
The angle measures of ABC and the other triangles are the same measures, and the side lengths in ABC and the other triangles are the same lengths when ABC coincides with them. It appears that angle measures and side lengths are both preserved when ABC is rotated.
An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex. Using a protractor, angles are measured in degrees (°). Fun facts Joseph Huddart created the protractor in 1801. It was a more advanced protractor.

Answer:
the answer is 1100
Step-by-step explanation:
you will do... 5500*20/100
(0, 15)
(10, 19.34)
m = (19.34 - 15) / (10 - 0) = .434
P(d) - .434d + 15
Answer: <em>x</em> = 20
Step-by-step explanation:
If line <em>m</em> is parallel to line <em>n</em>, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).
This means we will set them equal to each other and solve for <em>x</em>.
Given:
(4<em>x</em> - 23) = (2<em>x</em> + 17)
Add 23 to both sides of the equation:
4<em>x</em> = 2<em>x</em> + 40
Subtract 2<em>x</em> from both sides of the equation:
2<em>x</em> = 40
Divide both sides of the equation by 2:
<em>x</em> = 20
Simplify by dividing 19 by 4
the closest we can get is 16/4=4 and the remainder 3/4
so the piano is 4 and 3/4 foot long which is less than 5 so it will fit
