Answer 17

ya same here

Answer 18

too*

Answer 19

entering calc 1 and still have yet to memorize law of cosines... i feel so stupid

Answer 20

well to find the measure of B you need the law of cosines

\[\cos(B) = \frac{a^2 + c^2 - b^2}{2ac}\]

you know a = 14.1 , c = 20 and b = 8

substitute and calculate the answer

Answer 21

19°
34°
64°
127°
are the answers

Answer 22

well if you calculate it out... then you can find the answer

Answer 23

ok thansk @campbell_st

Answer 24

0.27 ugh i suck at this

Answer 25

i got 0.27

Answer 26

ummm I got

cos(B) = 0.948245

Answer 27

i dont get it ill guess

Answer 28

guesses on the questions and got 25/60

Answer 29

guessed *

Answer 30

well the calculation is

\[\cos(B) = \frac{14.1^2 + 20^2 - 8^2}{2 \times 14.1 \times 20}\]

Answer 31

i got that part

Answer 32

so you got 0.27 as the answer...?

Answer 33

\[\cos(B) = \frac{534.81}{564}\]
