Answer 4

Answer 5

do you know how to use sin and cos?

Answer 6

yes

Answer 7

This is much easier with 30-60-90 triangle rules and 45-45-90 triangle rules

Answer 8

I get weird answers with those rules :(

Answer 9

ok so were going to assume a=12 because algebra is easier than numbers lol. so to find z, we need the angle between a and z. do you know what that angle is?

Answer 10

30 degrees

Answer 11

\[\large \sf y\sqrt{3}=12\]\[\large \sf y=\frac{12}{\sqrt{3}}\] \[\large \sf z=2y\] Ez applications

Answer 12

so z would be 2 times\[12\sqrt{3}\]

Answer 13

Well \(\large \sf 2\frac{12}{\sqrt{3}}\)

Answer 14

the easiest method would be z*cos30=a where z = a / cos30 = 12/ cos30 or z= a/sin60

Answer 15

I'm so confused

Answer 16

this based on the relationships with right triangles and the unit circle

Answer 17

have you learned the unit circle yet?

Answer 18

or trig cirle. forget what its called

Answer 19

yes I have, but I barely understood it

Answer 20
