Answer for Blank 1:

Answer 3

I only got 1 and 2 but i was very confused on those and not very sure of my answers

Answer 4

@ScarlettFarra2000 @anthonyym can you help

Answer 5

I honestly have no idea how to calculate it but I guessed A is that right?

Answer 7

Thank you @satellite73 ! can you help on anymore please

Answer 8

Ok the triangle for question 1:
Now you have the opposite angle as well as the hypotenuse, so which trig function would you use?

Answer 9

Honestly, I dont know

Answer 10

Sorry meant opposite side

Answer 11

SOHCAHTOA
Sine = Opposite/Hypotenuse
Cosine = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent

Answer 12

So Sine?

Answer 13

Yes that's right.

Answer 14

So syou know sine of an angle = Opposite/Hypotenuse
Sin P = 33.8/57.6
Understand so far?

Answer 15

Kind of

Answer 16

The side Opposite to angle P is 33.8, and the hypotenuse (side opposite to the right angle and longest side) is 57.6.

Answer 17

Adjacent would be different just to let you know, it's the side right next to the angle (that's not the hypotenuse)

Answer 18

Do you still have questions?

Answer 19

yes, is the answer A ?

Answer 20

No, A is not the answer.
After you get Sin P = 33.8/57.6, you take the inverse/arcsine
Sin^-1 (33.8/57.6) = P

You can type Sin^-1 (33.8/57.6) into the calculator

Answer 21

i got .627018?

Answer 22

Yes that's the answer in radians, but the answer choices are in degrees. Make sure the calculator is in degree mode.

Answer 23

35.93?

Answer 24

Correct

Answer 25

THANK YOU SO SO MUCH!

Answer 26

can you help with any more?

Answer 27

Yes I could but I'll be quick because I have stuff to do.

Answer 28

Are you in trig/precalc by the way?

Answer 29

Okay I need help with 2,3, and 5 if that isnt too much but no I'm only in 8th grade soz

Answer 30

Oh wow ok I'm only introduced to csc, sec, and cot as sophomore 10th grade, but it's not hard at all and the same as SOHCAHTOA

Answer 31

Yeah, this is really really difficult for me oops I just don't get it tbh

Answer 32

Triangle for #2:

Answer 33

Do you know what csc, sec, and cot are?

Answer 34

I know cot is cotanget but thats about it

Answer 35

Ok,
csc is cosecant, the reciprical of sine, that means instead of Opposite/Hypotenuse, it's Hypotenuse/Opposite (you switch numerator and denominator for recipricals).

Answer 36

Secant (sec) is the reciprical of cosine, instead of adjacent/hypotenuse it's hypotenuse/adjacent
Cotangent (cot) is reciprical of tangent, instead of opposite/adjacent it's adjacent/opposite

Answer 37

Just to summarize:
csc = H/O
sec = H/A
cot = O/A

Answer 38

Okay that all makes sense

Answer 39

So now you can apply that to the question.

Answer 40

A seems true

Answer 41

First option: cot angle B equals 6 over 5
