5 0

Answer:

Step-by-step explanation:

Since ΔABC is right use the sine ratio to find AB

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ , hence

sin30° = $\frac{10}{AB}$ ( cross- multiply )

AB × sin30° = 10 ( divide both sides by sin30° )

AB = $\frac{10}{sin30}$ = 20 ft → C

Ahat [919]

Answer:

$2250

Step-by-step explanation:

First, find how much more Jayden will get each month by doing 2.5% of 5000, or multiplying 0.025 * 5000 = $125 per month.

Then, since Jayden is leaving it there for 18 months, you can do 125 * 18 = 2250.

The interest he will earn is $2250
