ABC is same as FDE
so AC = FE = 5ft
angle B = 28 deg
angle C = 90 deg
so A = 180 - B - C = 62
Answer:
In the first account was invested
at 3%
In the second account was invested
at 5%
Step-by-step explanation:
we know that
The simple interest formula is equal to
where

explanation: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
