A) area = length x width = 12 x 6 = 72 sq.cm
B) area = 1/2x base x height = 1/2 x 3 x 6 = 9 sq.cm
C) same as B= 9 sq. Cm
D) subtract area of both triangles from area of rectangle:
72 - 9 -9 = 54 sq. Cm
perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10

The question is asking you to find the measure of YZ's arc.
The arc of a circle is found by finding the central angle. In this case, that's angle YCZ. Remember that a circle's total degrees is 360. Since the angle that you are trying to find is 16% of the circle, you need to find 16% of 360.
360*0.16 = 57.6
The measure of arc YZ is 57.6 degrees.
