the sum of all interior angles in a polygon is 180(n - 2), where n = number of sides.

well, this is a quadrilateral, so it has 4 sides so it has a total of interior angles of 180(4-2) = 360°, since this is a kite, then <u>one pair of opposite angles are congruent</u>, namely ∡C = ∡A.

360° - 45° - 100° = 215°, and ∡C and ∡A split that evenly, so ∡C = 107.5°.

A piano has 52 white keys. Write and use an equation to find the number of octaves on a piano keyboard.
Firdavs [7]
There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets
