Answer: Question 18= 135, Question 19= 540
Step-by-step explanation:
Hello there! So you were right for number 18! It is for sure 135. This is because these are alternate exterior angles which are always congruent(the same).
Number 19 is confusing however. So a pentagon is a 5 sided shape as we know. From a vertex that we will call A, we can draw two diagonals which will then separate it into triangle. 3 of them to be exact.
We are trying to find the sum of all the interior angles and we know that a triangle has a sum of 180 degrees, so since there are three, we multiple it by three.
We then get 540 degrees.
Hope this helped! Sorry if I didn’t explain it well! :(
<span>The future amount of money that is invested currently at a certain interest that is compounded annually is calculated through the equation,
F = P x (1 + i)^n
where F is the future worth, P is the present worth, i is the interest rate, and n is the number of years. Substituting the known values and variables in the given,
F = ($360)(1.03)^x</span>
