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°.
1. The cube root of 384 can be rewritten as the cube root of (8*48). That can be simplified to 2 cube root of 48. That can be simplified down further to 2 cube root of (6*8), which is 2*2 cube root of 6, or 4 cube root of 6. So, the answer is C.
You do the same thing for each of the problems. If you actually want me to just give you the answers, they are:
1. C
2. D
3. D
If you need work, ask me in my inbox.
D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
