Answer:
8.38
Step-by-step explanation:
The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.
I think you can use cosine rule if only the lines that form the <52 are equal.
Answer:
C. 364.4
E. 14
F. 21
G. 96°
It would be 66 degrees because
this would equal 180 degrees
add the angles together:30+57+27=114
now subtract 180-114=66degrees
FINAL ANSWER:66degrees
