Question

suppose angle B=60 degrees, and length of b=2

Answer 1

what have you tried? :)

Answer 2

angle a is 30 degrees

Answer 3

which means b is 60 degrees

Answer 4

A=30 is correct,
B = 60 is given,
go on

Answer 5

tan30=a/2

Answer 6

2*tan(30)=a/2

Answer 7

a =2 tan 30

Answer 8

which is 1.15 which is just 1

Answer 9

they want the exact measures

Answer 10

since we are not allowed decimals,
whats tan 30 in fraction ?

Answer 11

1/sqrt3

Answer 12

or
lets try to get 'c' first using sin B

Answer 13

ok,
thats correct, so a = 2/\sqrt 3

Answer 14

\(a= \dfrac{2}{\sqrt 3 }\)

Answer 15

so sin60=2/c, 2*sin60,

Answer 16

sin of 60 degrees is sort(3)/2

Answer 17

sqrt*

Answer 18

yes

sqrt 3/2 = 2/c


so c = 2*2/ sqrt 3 = ...

Answer 19

4/sqrt(3)

Answer 20

\(\huge \checkmark \)

Answer 21

so basically we are transforming the degrees into the coordinates of either sin or cos .. i'm slow :)

Answer 22

i didn't get that :P

we are trying to find the missing angles and sides of a triangles using sin/cos/tan ....

Answer 23

but every coordinate on the unit circle has either a sin and cos.. just clarifying :D

Answer 24

yes, that is true!
