Question

solve the following triangle, round length to nearest tenth, round angle to nearest angle. a=5,b=6,c=8

Answer 1

use cosine rule to find any angle, then use sine rule to find th second, then just use geometry to find the third

Answer 2

i got angles a=39,b=49,c=93 is that correct?

Answer 3

hold on and ill upload a picture

Answer 6

change the radians to degrees

Answer 7

i can google that myself, i know the steps. that site doesnt say if my steps are right.

Answer 8

besides, that site doesnt even give me a solution, thanks for your help i guess

Answer 9

if you don't get that answer, then you did something wrong

Answer 10

yes it gives the solution, multiply by 180/Pi

Answer 11

it doesnt show me an answer!

Answer 12

scroll down to the angle

Answer 13

i need all angles lol, not one

Answer 14

it has all three

Answer 15

interior angles |~~(0.674131 radians | 0.846645 radians | 1.62082 radians)

multiply each by 180/pi

Answer 16

it would be more helpful if you clicked on my solution and see if i got it right, if not tell me where i went wrong

Answer 17

38.6, 48.5, 92.866

Answer 18

your answers are correct

Answer 19

perl look at this, one moment

Answer 20

ok

Answer 21

did you check my math or jus the steps i followed?

Answer 22

so you think the answer choices is a mistake? or do you think i made a mistake?

Answer 23

we want the angle between side 5 and side 6

Answer 24

yes thats what i used law of cosine on first

Answer 25

i got 93 degrees there

Answer 26

C should be 49

Answer 27

can you take another picture of your work, its kind of small

Answer 28

can you blow it up into two parts , maybe
or use more light

Answer 29

i have a piece of junk monitor

Answer 30

angle c is clearly not 49 degrees. that is an obtuse angle, hence it is opposed to the longest side. 49 degrees is small

Answer 31

that angle c is close to 90 just by a guess by looking at it

Answer 32

very close to a square angle

Answer 33

that drawing is not drawn to scale

Answer 34

no to scale but if the angle c is opposed to the longest side, it is the biggest angle of the triangle. its not to scale, but is the right porpotions

Answer 35

wait

Answer 36

lets see how you came up with 49 then

Answer 37

one second, rewind

Answer 38

this wont be the first mistake on the quiz so dont rule that out. it will be like 4 mistakes of 19 questions so far
