You may recognize that ∆WYZ is a 3-4-5 right triangle. Without any work, then
c = 5
_____
If you don't remember that a right triangle with legs 3 and 4 has a hypotenuse of 5, you can compute it using the Pythagorean theorem.
c² = 3² + 4²
c² = 9 + 16 = 25
c = √25 = 5
Answer:
a. earned: $292.50
b. total: $2,092.50
Step-by-step explanation:
A = 1800 [1 + (0.065 * 2.5)] = 2092.5
A = $2,092.50
To find the amount is earned, subtract the total with how much to started with
