The answer is 51.3
Explanation:
You’re finding angle Y, so write the SOH CAH TOA. the two sides your are given are the adjacent side to Y and the opposite side so you use tangent. You then get the equation tanY=10/8 Since you’re finding an angle you use inverse tangent so you get y=tan^-1(10/8) and then put that into the calculator!
Answer: y= -2 (x+1)
Step-by-step explanation:
this would be the “inverse” of the original equation making them cross at exactly 1 point
I believe the answer is 8.54, if you take 42.70 and multiply it by 20% you get 8.54!
