Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. A = 56°, a = 12, b = 14

OpenStudy (dumbcow):

|dw:1408123283590:dw| \[\frac{\sin B}{14} = \frac{\sin 56}{12}\] in solving for B you will get 2 possible solutions which leads to two different triangles

OpenStudy (wade123):

is B = 75.3° right?

OpenStudy (dumbcow):

yes and the other possible solution will be in 2nd quadrant

OpenStudy (wade123):

B = 75.3°, C = 48.7°, c = 13.2; B = 104.7°, C = 19.3°, c = 13.2

OpenStudy (wade123):

thats what i got

OpenStudy (wade123):

right?

OpenStudy (dumbcow):

angles are correct but length "c" is wrong

OpenStudy (wade123):

i had a feeling

OpenStudy (wade123):

B = 75.3°, C = 48.7°, c = 10.9; B = 104.7°, C = 19.3°, c = 4.8 this is correct right?

OpenStudy (dumbcow):

the smaller the angle, the shorter the opposite side so we know that c is less than 12

OpenStudy (wade123):

it is 4.8 right?

OpenStudy (dumbcow):

yes that is correct ...lol you just posted different options from multiple choice question huh

OpenStudy (wade123):

thank you so much!

OpenStudy (wade123):

and nope i post questions that i dont know from my review so i can prepare myself for the exam (:

OpenStudy (wade123):

Find all polar coordinates of point P where P =

OpenStudy (wade123):

can you help me on this one too?
