What do you need help with. I am really good in math
Find Angle B: B = 180 - (82+55) = 43. Then apply the law of sines:
b 8 cm
--------- = ----------
sin 43 sin 55
(sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).
sin 55
Answer:
29
Step-by-step explanation:
You need to find the average number of students
Add up all the students
27+31+28+33+26
145
Divide by the number of classes
145/5
29
The average is 29
I think it's the first option
Given A= {1,2,3,4,5,6,7,8,9} and B={2,4,6,8}, what is A U B?
Ugo [173]
A u B = { 1,2,3,4,5,6,7,8,9}
All elements of both sets , if they are repeating , you don't have to write them twice.
