Answer:
∠ACD= 109°
Step-by-step explanation:
∠A=38
180- ∠A= ∠B+C
180-38= 2∠B( ∠B=∠C) ( angles opposite to equal sides are equal)
142=2∠B
∠B=71
∠ACD=∠A+∠B ( exterior angle property)
∠ACD= 38+ 71= 109°
set 2x-3 equal to 0 and solve for x
x=3/2
set x+5 equal to 0 and solve for x
x=-5
the solution is the result of 2x-3=0 and x+5=0
x=3/2,-5

The standard form representation is

Now we need to obtain
in such a way that

In standard form
Since

This means

Now looking at the z-table for probability of 0.99 we obtain 1.88
i.e
Making 



The answer to that would be 7/2.
