The answer is A because u can subtract the 3x to get 2y by itself then divide by 2 to completely get y by itself and it would be y=-3/2x - 9/2
The vertex would be (-2,4)
5, 10 ,15
divide each by 5
1,2, 3
so the ratios should be 1,2,3
Metal 1 : divide by 150
1,2,4
Metal 2 divide by 130
1,2,3
Metal 3 divide by 310
1,2,3
Metal 4 divide by 140
1,2,3
Metal 1 is not proportional
Choice A
A trapezoid is a quadrilateral which means the sum of the angles should be equal to 360 degrees. The other angles therefore should have the sum of 360 - 60 - 45 = 255 degrees. Since we do not have the figure it would be hard to specify the measure of each angle.
