Question

2. solve the triangle below by finding all missing sides and or angles
part1: find the length of side AC. round your answer to nearest hundreths
part2: find the measure of angle C
part3: find the measure of angle A using any method

Answer 1

Use the law of cosines

Answer 2

AC^2=AB^2+BC^2-2*BC*AB*cos(B)

Answer 3

You can then use the law of sines to solve the rest of it

Answer 4

yes use law of cosines to find AC

then using law of sines
sin(C)/10 = sin(110)/AC

Answer 5

how do i find the AC BC AB in order to use the formula tho?

Answer 6

???

Answer 7

AB = 10
BC = 8
angle B = 110

Answer 8

well duh tdiaz100, lol okay let me solve it

Answer 9

haha ok:)

Answer 10

323.84

Answer 11

????

Answer 12

for AC, no

Answer 13

ok i know question 2 and 3 is 35 degrees

Answer 14

Take the square root

Answer 15

it has to be less than 18

Answer 16

17.99

Answer 17

i round to the nearest hundreths would it be 20?

Answer 18

something went wrong

=100+64-2(80)cos(110)

Answer 19

were the 80 came from?

Answer 20

10*8

Answer 21

same thing 17.99

Answer 22

14.79

Answer 23

no that would mean the angle is like 179 degrees

Answer 24

is your calculator in degree mode?

Answer 25

haha yeah thats what it is

Answer 26

yes it was

Answer 27

If i put mine in radian mode, i get 17.9956. in degree mode, i get 14.7893

Answer 28
