Question

Suppose angle A=pi/3 radians and length of c=10

Answer 1

you have b and c,
use pythagoras to find a !

Answer 2

the interior angles are b=30, and a=60

Answer 3

right,
so you can also use the fact that,

side opposite to 60 degree angle is \(\sqrt 3 /2\) times the hypotenuse

Answer 4

For the length of a I tried setting up sin60=a/10

Answer 5

ok, good going,

so a = 10 sin 60

and sin 60 is actually \(\sqrt 3 /2\)

Answer 6

so i'm a little confused what i'm supposed to do with the Sqrt(3)/2

Answer 7

multiply it with 10
\(10 \dfrac{\sqrt 3}{2} = 5 \sqrt 3 \)

Answer 8

oh I see, so instead of using the 60 degrees we are just multiplying sqrt(3)/2 by 10

Answer 9

yeah

Answer 10

makes sense! Thank you lots :D

Answer 11

welcome a lots ^_^
