Answer 1

with

Answer 2

Do you remember the soh cah toa thing we talked about earlier?

Answer 3

Kind of, I hate IXL because it's so precise...but I'm worse with ratios, fractions, and radicals

Answer 4

to find RS, which is the opposite side
Which of sine, cosine, and tangent should we use

Answer 5

Um...Sine

Answer 6

Yep~
So how would we write out the equation

Answer 7

OKay, Sin(30)=RS/2

Answer 8

yep
So now put into your calculator
sin(30) times 2

Answer 9

i think you need to divide 30 and two

Answer 10

Nope sin(30) is together
So first do sin(30) then multiply it by 2

Answer 11

for rs??

Answer 12

−1.976063

Answer 13

?

Answer 14

That's probably in radians
Recheck, do it in degree mode

Answer 15

okay

Answer 16

oops
I forgot to tell you something
30, 60, 90 degrees, it is a 1, 2, sqrt3, triangle, which means that RS is 1, and the other unknown side is sqrt3
There are also 45, 45, 90 triangles, which are 1, 1, sqrt 2, sides

Answer 17

sin(30) is 0.5, so times 2 is 1
