Answer:
Choice B. sin(B)=cos(90-B)
Step-by-step explanation:
That cofunction identity is the one you looking for...choice B.
If you aren't convinced or don't know that identity, then maybe this will help:
90-B is actually the same thing as saying A for this right triangle since A+B=90.
So choice B basically says sin(B)=cos(A)
Well let's find both sin(B) and cos(A)
sin(B)=b/c
cos(A)=b/c
Those are the same ratios!
So they are equal!
The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!
