Diana invested $3000 in a savings account for 3 years. she earned $450 in interest over that time period. what interest rate did she earn? use the formula l=prt to find your answer , i=interest , p=principal and r=rate and t=time. write answer in decimal form

The interest rate is 0.05

Step-by-step explanation:

i = $450

p = $3000

r = r%

t = 3yrs

450 = (3000×r×3)/100

45000 = 9000r

9000r = 45000

r = 45000/9000

= 5%

= 0.05

b is 38 degrees.

a is 52 degrees.
