Answer:
C) 5/13
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the cosine ratio is ...
Cos = Adjacent/Hypotenuse
For the given problem, this means ...
cos(B) = BC/BA = 15/39
cos(B) = 5/13
Answer: he has read 15% and still needs to read 85%
Step-by-step explanation: 300/20 is 15 so that’s the percent he has read. 100-15=85 so that’s the percent he still has left to read
You need to change 15% to a decimal and multiply it by 25
25 x 0.15 = 3.75
Then add 3.75 to 25 to get the total
25 + 3.75 = 28.75
So, the answer is 28.75$
