Question

@tjb69812  my answers are also on the image along with the questions.

anonymous · Answer

OK. So for #9

 a^2+b^2=c^2

1^2+1^2=c^2

c = sqrt 2

anonymous · Answer

Then from here: sin(a) = 1 / sqrt2

anonymous · Answer

Wait I have to solve it? I thought I just had to write the equation?

anonymous · Answer

Since sin = opposite / hypotenuse you need to find the hypotenuse

anonymous · Answer

well the direction told me to use the given triangles to identify the trigonometric ratios.
i thought that meant the equation... wow.. okay back to what you were saying.

anonymous · Answer

SOH - sin
CAH - cos
TOA - tan    if you haven't learned this it's very helpful!

anonymous · Answer

I have learned that :]

anonymous · Answer

cos(a) = 1/sqrt2

anonymous · Answer

sin(b) = 1/sqrt2

anonymous · Answer

cos(b) = 1/sqrt2

anonymous · Answer

I think I see now what you're doing.. thanks again!

anonymous · Answer

No problem! Now apply that to #10. Practice makes perfect
