Question

Suppose angle A=pi/4 radians and length of b=3

Answer 1

since angle a is pi/4 radians angle a is 45 degrees

Answer 2

and angle b is 45 degrees

Answer 3

ohh i like pi/4 angle

the angles become congruent and 2 sides become equal :P

Answer 4

:D I set up tan45=a/3

Answer 5

and got that a=3

Answer 6

correct

Answer 7

since it's a 45-45-90 triangle a and b are both 3

Answer 8

agreed

Answer 9

so 3^2+3^2=c^2, 9+9=c^2, 18=c^2 i'm not sure if we need to get square root of 18

Answer 10

ok, lets use a trig function then

find sin A or sin B

Answer 11

so sin(45)=3/c, c=3*sin45 which is 2.12

Answer 12

you can keep it as
\(3/ \sqrt 2\)

Answer 13

where did we get the 3/sqrt of 2 from? lol

Answer 14

because it is mentioned, "no decimals"

Answer 15

sin 45 = 1/\(\sqrt 2\)

3 sin 45 = 3/\(\sqrt 2\)

Answer 16

sin of 45 =sqrt(2)/2..
