Answer 1

a.
44.5
c.
49.4
b.
33.6
d.
77.1

Answer 2

hmm well. if you're using the "law of sines', that may not give you that much, since you only have one angle and its side is missing

even if you were to find the side "b", how are you meant to get the area?

Answer 3

no idea thats just what the question asks

Answer 4

well. have you covered the law of sines?

Answer 5

or have you covered the law of cosines?

how about heron's formula?

Answer 6

no idea on any of that

Answer 7

i know the law of sines formula

Answer 8

i got c for this question is that right

Answer 9

how did you get "c", if you dunno any of the sections above?

Answer 10

49

Answer 11

i just said i know law of sines

Answer 12

anyhow, in this case what I'd use is the law of cosines, and then heron's formula
but you haven't covered either, thus, you may want to do that firstly

check your material for both, otherwise, I'd say the exercise doesn't apply to you

Answer 13

the law of sines alone in this case, is not help, because side "b" is missing

Answer 14

1/2 * (10.1*9.8 SINS 87) and i got 49

Answer 15

1/2 base * height, to get the area of a triangle, only applies to right-triangles

this one doesn't come across to me to be one

Answer 16

well.. .I take that back

1/2 base * height does apply to all triangles
BUT

we dunno the triangles altitude, or height in this case, just its base

Answer 17

well i got 49 and thats an option so thats what im putting

Answer 18

i dont know how else to answer it

Answer 19

if it were a right-triangle, it'd simple to just grab either side and use it as altitude
but angle B is 87 degrees, not 90

Answer 20

I myself, don't see how the law of sines alone would do it in this one

I'd use the law of cosines to find "b", and use that in Heron's formula to get the area

Answer 21

the test is titled LAW OF SINES

Answer 22

then whats the law of cosines forumula

Answer 23

doesn't matter, you need to cover that first

but surely your book would have it

Answer 24

im not in a book im taking an online test

Answer 25

can you just help me

Answer 26

thats why im here

Answer 27

well,, surely it has studying material, so


you see, the issue is, if the material hasn't been covered, there's no sense in giving the exercise

I've heard some folks say that, online classes and such, I don't see how that exempts them from studying

now, it may be that the site is giving you something that hasn't been covered
but if you haven't covered something, there's no sense in giving you the exercise
