Question

In ΔABC, BC = 12.35, AC = 8.75 centimeters, and m∠B = 37°. What are
m∠A and m∠C to two decimal places?

m∠A ≈ 25.24°, m∠C ≈ 117.76°

m∠A ≈ 58.15°, m∠C ≈ 84.85°

m∠A ≈ 25.24°, m∠C ≈ 64.76°

m∠A ≈ 58.15°, m∠C ≈ 31.85°

Answer 1

law of sines

Answer 2

you got a picture? look like a law of sines problem

Answer 3

Do you know how to solve a law of sines problem?

Answer 4

no there wasnt one its just hard for me

Answer 5

a/sinA = b/sinB = c/sinC

Answer 6

These ratio's each have the same total

Answer 7

So the first thing we need to do is find the ratio

Answer 8

so we can find with b/sinB

Answer 9

can you find that?

Answer 10

b = 8.75
B = 37

Answer 11

i really forgot i stink at math

Answer 12

8.75/sin(37)

Answer 13

what is the answer to that?

Answer 14

-13.5967078662

Answer 15

no, put your calculator in degree mode

Answer 17

So the ratio is 14.5

Answer 18

14.5393512348

Answer 19

ya

Answer 20

ok got that

Answer 21

so now we can find the angles

Answer 22

lets find A first

Answer 23

how do we do tht

Answer 24

a/sinA = 14.5

Answer 25

look at the triangle and tell me what 'a' is

Answer 26

the neasure of AC is 8.75 but it doesnt have an angle measure
