Line CA is a straight line, meaning it adds up to 180°

Line BE splits the line into two supplementary angles, because when the two angles are added together they will equal 180°

Using the rule of supplementary angles, we can then make the equation 3x + 8x + 15 = 180

Now, simplify the equation by combining like terms

11x + 15 = 180

To solve, isolate x

11x + 15 = 180
11x = 165
x = 15

Adam drew two same size rectangles and divided them into the same number of equal parts. He shaded 1/3 of one rectangle and 1/4

MArishka [77]

he divided each rectangle in 12 identical parts

for the first rectangle he shaded 1/3 of 12 = 4 parts

for the second rectangle he shaded 1/4 of 12= 3 parts

so 12= 3*4 leads to a minimum of 12 parts
