Vertices A and B of triangle ABC are on one bank of a river, and vertex C is on the opposite bank. The distance between A and B
AURORKA [14]
A suitable solver will tell you instantly that the measure of b is 179.18 ft.

_____
If you want to do it yourself (meaning also with the aid of a calculator), you can use the Law of Sines. The given side is side "c", so you need the measure of angle C. That will be
  180° -33° -63° = 84°
Then side "b" can be found from
  b/sin(B) = c/sin(C)
  b = c*sin(B)/sin(C)
  b = (200 ft)*sin(63°)/sin(84°) ≈ 179.183 ft

Darren invests $750 in an account that pays 2.5% simple interest for 40 weeks. How much will his investment be worth at the end
Yuliya22 [10]

Answer:

  $764.42

Step-by-step explanation:

The account balance is given by the formula ...

  A = P(1 +rt)

where P is the principal invested, r is the annual rate, and t is the number of years. Here, we assume 52 weeks in the year, since the time period is given in weeks.

Filling in the numbers, we have ...

  A = $750(1 +0.025(40/52)) = $764.42

Darren's investment will be worth $764.42 at the end of 40 weeks.
