ABCD is a quadrilateral. a) Calculate the value of x.
A = 2x
B = 90 Degrees
C = X
D = 3x

360 - 90 = 270
270 ÷ 3 = 90
270 ÷ 2 = 135
135 - 90 = 45

x = 45 Degrees

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04
