That whole angle is supplementary and we’re given 90 and the 73 is a vertical angle. 90 + 73 is 163 and 180 - 163 = 17
X = 17
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Area of the trapezium = 1/2(18 + 6) x 12

The graph is important especially for the people who presenting something like the businessman or marketing personnel. The graphs summarizes the raw data and presents it into a diagram for the people to be easily comprehend. It allows to us to see the relationship between the variables.
