A steel support beam h = 33 foot in langth is positioned in the center of the garage. To support the roof another beam will be attached to the top of the center beam (se the figure). Al what angle of elevation is the new beam? In other words, what is the pitch of the roof?​

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
