Answer: the correct answer is A. :-)
Step-by-step explanation:
4/9 divided by 4 is 1/9.
Statement 3: tri egc = tri egb
statement 4: tri ebc is equilateral.
reason 5: equilateral triangles have equal angles
A circle is 360°. Since you only have 3 different types of weather, if you split the ° equally, each section would have 120°. The amount of rainy days is 10/30 or exactly 1/3, so 120° are rainy days.
If you do 30 x 12, it equals 360. So that means that each day is 12°. There were 8 cloudy days, so you can do 8 x 12 = 96°
5/8 * 4/5
5*4 20 1
----- = ----- = ---
8*5 40 2
5/8 * 4/5 = 1/2 or .5
