We are told that Carrie borrows $960 interest free to pay for a car repair. She will repay $120 monthly until the loan is paid off and we are asked to find how many months will it take Carrie to pay off the loan.
In order to find out the number of months to pay off the loan we will divide total amount borrowed by monthly loan installment.
Therefore, Carrie have to pay $120 for 8 months to payoff the loan.
Answer:
B) A = 52.3°, b = 1.7 m, c = 2.8 m
Step-by-step explanation:
We know that it is a right angle triangle because C = 90°
because of that we can do 180 - 90 + 37.7
which is a=52.3
Because it is a right angle triangle, we can use sin, cos,tan
I will use sin to find the side of c
2.2 is a
sin 52.3 = 2.2/x
x= 2.2/ sin 52.3
x=2.78
You could do cos or tan but the pythagorean theorem for me is much faster
so it looks like this, a^2+b^2 =c^2
in this case we have both a and c we want b
so we rearrange
c^2-a^2=b^2
2.78^2-2.2^2= b^2
=b
1.7=b
therefore it would be this option B) A = 52.3°, b = 1.7 m, c = 2.8 m
