By angle:
We can classify a triangle 4 different ways when we're judging it by it's angle(s).
Acute: A triangle where all angles are less than 90 degrees.
Obtuse: A triangle where one angle is greater than 90 degrees.
Right: A triangle where one of the angles is exactly 90 degrees.
Equiangular: A triangle where all angles are the same (60 degrees.)
We can also classify a triangle by its sides:
Equilateral: (technically the same as an equiangular triangle, in order to have 3 equal sides you must have 3 equal angles as well.)
Isosceles: Two sides are the same length, where one is not.
Scalene: All three sides are different lengths.
I hope this helps!
Answer:
$110.37
Step-by-step explanation:
Assuming the monthly payment is made at the beginning of the month, the formula for the monthly payment P that gives future value A will be ...
... A = P(1+r/12)((1+r/12)^(nt) -1)/(r/12) . . . . n=compoundings/year, t=years
... 14000 = P(1+.11/12)((1+.11/12)^(12·7) -1)/(.11/12)
... 14000 = P(12.11)((1+.11/12)^84 -1)/0.11 ≈ P·126.84714 . . . . fill in the given values
... P = 14000/126.84714 = 110.37 . . . . . divide by the coefficient of P
They should deposit $110.37 at the beginning of each month.
