Sum of exterior angle of a polygon is 360
90 + 10x + 5x + 45 = 360
135 + 15x = 360
15x = 360 - 135 = 225
x = 225/15 = 15
Largest exterior angles = 10x = 10(15) = 150 degrees.
I think you should say you multipliyed?
Width: W
Length: L = W + 8
Perimeter = 2W + 2L = 2(W) + 2(W+8) = 184 (ft)
Solving for W: 2W + 2W + 16 = 184 (ft)
4W = 168 ft, and so W = 42 ft.
The length, L, is (42 + 8) ft = 50 ft. (answer)
Answer:
P(blue) = 0.33
P(green) = 0.14
P(purple) = 0.24
P(yellow) = 0.29
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
7+3+6+5 = 21 tils.
7 of them are blue. So
P(blue) = 7/21 = 0.33
3 of them are green. So
P(green) = 3/21 = 0.14
6 of them are yellow. So
P(yellow) = 6/21 = 0.29
5 of them are purple. So
P(purple) = 5/21 = 0.24
