Answer:
Length of base (a) = 5 units
Total Surface Area of Pyramid (T.S.A.) = ?
Now,
T.S.A. = Area of four triangles + Area of base
= 
≈ 
The coordinates of the midpoint are just the average of the endpoint coordinates ...
x-mid is the average of the end-x's, and y-mid is the average of the end-y's.
P. x = 0, y = 8
Q. x = 4, y = 2
'x' of the midpoint is the average of 0 and 4 = (1/2)(0 + 4) = 2
'y' of the midpoint is the average of 8 and 2 = (1/2)(8 + 2) = 5
The midpoint is (2, 5) .
That's choice-'c'.

<u>Statement Reason </u>
BA and BC opposite rays Given
AC is a straight line Definition of opposite rays
∠ABD + ∠CBD = ∠ABC Angle addition postulate
∠ABD + ∠CBD = 180° Definition of linear pair
m∠ABD = 5x + 7 Given
m∠CBD = 9x + 19 Given
5x + 7 + 9x + 19 = 180 Substitution property of equality
14x = 180 - 26 Subtraction property of equality
x = 154/14 Division property of equality
x = 11 Proved
