For #19 part A :
By vertical angles and then same side interior angles 3x + 2x = 180
5x = 180
x = 36
For #19 part B:
You are correct with the 35, but you missed the fact that the 105 angle is supplementary with the unknown angle inside the triangle. So:
180 - 105 = 75
Then:
180 = 35 + 75 + x
180 = 110 + x
x = 70

Answer:</h2>
The simple interest is calculated only on the principal amount of a loan so it is relatively easier to calculate than the compound interest.
The compound interest is calculated on the principle amount plus the interest that the amount gets per compounding period up to the period of the loan. In other words, in compound interest we get, interest on interest.
This difference between the both, is the reason, we get more money in compound interest than simple one.
Let us take an example-
Suppose the principle is = $5000
r = 5% or 0.05
t = 5 years
Simple interest formula is :

=> 
So, total amount after 5 years will become =
dollars.
-----------------------------------------------------------------------------------------
Lets check for compound interest where the interest is compounded annually.
p = $5000
r = 5% or 0.05
t = 5 years
n = 1
Compound interest formula is :


=>
A = $6381.40
--------------------------------------------------------------------------------------------
We can see that we are getting more money in compound interest than the simple interest, for the same amount and same time period.
