Answer:

d = 14

Step-by-step explanation:

\sin \: 45 \degree =  \frac{a}{7 \sqrt{2} }  \\  \\a = 7 \sqrt{2}  \sin \: 45 \degree  \\  \\ a =  7\sqrt{2}   \times  \frac{1}{ \sqrt{2} }  \\  \\ a = 7 \\  \\  \sin \: 30 \degree =  \frac{a}{d}  \\  \\  \frac{1}{2}  =  \frac{7}{d}  \\  \\ d = 2 \times 7 \\  \\ d = 14

Suppose that an account earns 5.9​% interest and after 2 years the balance is $ 4472. Find the principal that was invested. Use
Marizza181 [45]

Answer:

The principle amount = $4000

Step-by-step explanation:

Formula:

Simple interest I = PTR/100

P - Principle amount

T - Number of years

R - Rate of interest

<u>To find principle amount</u>

Here , P = ?, T = 2 years, R = 5.9% and p + I = $4472

I = PTR/100

P + (P*2**5.9)/100 = 4472

P[1 + 11.8/100] = 4472

P[111.8/100] = 4472

P = (4472*100)/111.8 = 4000

Therefore the principle amount P = $4000
