I think that you are mistaking the memory tool for something else
or a math book is trying to make math cute by calling them 'socatoa joe' and 'mr. pi' and such
anyway, SOH, CAH, TOA is the way to remember
Sine=oposite/hypotonuse
Cosine=adjacent/hypotonuse
Tangent=oposite/adjacent
(oposite side=side oposite the angle
adjacent is the side touching the angle that is not they hypotonuse
and of course the hypotonuse is the longest side aka, side oposite right angle)
Answer:
x= -
Step-by-step explanation:
First move the x on the right side the the left side. Now your equation is
2x+= Next move 1/2 to the right side. Now your equation is 4x=. Next divide both sides by 4 to isolate "x." Now your equation is x= -
Hope this helped and have a great day.
