Answer:
22 degrees to the nearest degree.
Step-by-step explanation:
Use the Cosine Rule
3^2 = 5^2 + 7^2 - 2*5*7*cos T
9 = 74 - 70 cos T
cos T = (74-9)/ 70
cos T = 65/70
m < T = 21.8 degrees.
Answer:
I read it.. I don't know.. It's just saying we can't really cheat, it's not too bad.
You can approach this question in multiple ways, 2 of which are more obvious.
Method 1). Add up the number of marbles which aren't white divide that by the total number of marbles.
I.e. 8 + 14 + 10 = 32
32/48 = 2/3
[There are 48 marbles in total]
Method 2). Find the total number of marbles, divide the number of white marbles by the total (like method 1), then do 1 minus the answer.
I.e. 16/48 = number of white marbles
1 - 16/48 = 2/3
Answer:
1/6 x 1/6 x 1/6 = 1/36 x 1/6 = 1/216
