20 points find the measure of ∠d if ∠a = 5/2x + 30 ∠b = 7/2x + 40 ∠c = 9/2x + 10 ∠d = 5/2x + 20 awnser choices a) 60° b) 70° c) 80° d) 100°

i need a picure

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
