In the figure below, ABC is a right triangle. a+b= 150 degrees, and c+d= 35 degrees. Find x.
2 answers:
Alright, lets get started.
These two triangles ABC and ACD are jointly forming a polygon having 4 sides ABCD.
The sum of all internal angles of a polygon having 4 sides = 360
∠A + ∠B + ∠C + ∠D = 360
Plugging the values of each angle
Subtracting 275 from both sides
°
Hence the option is C. (85) : Answer

Using compound interest and a graphing calculator, it is found that it will take about 15 years for the loan to be paid off.
<h3>What is compound interest?</h3>The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
For this problem, the parameters are given as follows:
A(0) = 95000, r = 0.06, n = 12.
Hence the value of the loan after t years is:
You have monthly payments of $1,200, hence the amount paid after t years is:
P(t) = 12 x 1,200t = 14400t
Then we have to solve for:
A(t) = P(t)
Which is solved in the graph below, meaning that it will take about 15 years for the loan to be paid off.
