Not completely sure what you’re asking but y=3.5x has the sharpest rise and out of the bottom four y=3x does
Answer: ?=7
Explanation: Use pythagorean theorem
Let a =70° and b= 10° (and a-b=70-10 =60)
We have the following trigonometric identity:
sin(a-b) = sin(a).cos(b)-sin(b).cos(a) OR:
sin(70-10) = sin70.cos10 - sin10.cos70
But sin(70-10) = sin(60) and we know that sin(60°) =(√3)/2
