Find the values of x and y in the d

9514 1404 393

Step-by-step explanation:

The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.

  UT = RS

  x -5 = 15

  x = 20 . . . . . . add 5

__

ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.

  3y = 30

  y = 10 . . . . . divide by 3

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
