You'd want to buy the 4 by 5 and the 11 by 14 because if you times 4 by 3 and 5 by 3, the answer would be 12 by 15 which is the closet or the most similar pair
Number 1: To find number 1 use hypotenuse theory. 180-(69+31) is the equation. After you solve it you get m<1 as 80.
Number 2: Since you already found m<1 find the other angle across from it.
Equation is: 180-80, which equals to 100.
Then once you have two angles use the theory again: 180-(100+45)=35.
Therefore m<2=35.
Number 3: Still using m<1, 180-100=80. Now you have to angles you get the equation:
180-(80+47), which equals to 53. Therefore m<3=53
Answers: m<1=80; m<2=35; m<3=53
Answer
After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.
Explanation
Using the given equation A = P(1 +r)^t
We are given that our initial start is $500.
P = 500
We are further told that the percentage interest gained is 12%, so we need to convert this into a decimal to be able to work with it.
12% / 100% = 0.12
r = 0.12
t is then our time in years
t = 10
A = 500(1 + 0.12)^10
A = 500(1.12)^10
A = 500(3.1058)
A = 1,552.92
After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.
