Triangle method to solve equations By Marie Lyle Science Equations d=st Distance=speed x time V=IR Voltage=Current x F=ma Resistance Force=mass x acceleration Mass=density x volume m=dv Set up the triangle for the distance equation. D=ST The variable on the left (D) goes on top. The variables on the right (S and T) go on the bottom. Plug in the given values If the given values are next to each other (S and T) multiply to solve for D. If the given values are above one another, divide the top number by the bottom number to solve for S or T. Hint: Cover the unknown. Then multiply or divide to solve. Any equation in the a=bc format can be solved with a formula triangle Watch this animation to see how it works. http://www.revisionhut.co.uk/page10.html
