The z-score will be found as follows:
P(-z<Z<z)=0.18
P(-z<Z<z)=0.18/2=0.09
P(Z<0)=0.5
P(Z<z)=P(Z<0)+P(0<Z<z)=0.5+0.09=0.59
From the z-table, the z-value will be:
z=0.23
BC is 6.08, use distance formula to calculate
height is BE and also 6.08
AD is 18.25
A= h((a+b)/2)
=6.08(6.08+18.25)/2)
= 73.96 units^2 is the area
Area of a triangle =

.
a=7
b=10
The largest possible value for sin(C) is 1, which is sin(90)
So area =
The answer is A
Explanation
First you had to divide by p from both sides of equation form.

Then simplify by equation.

Final answer:
