Step-by-step explanation:
Answer: He will have 3,200 in 5 years.
Step-by-step explanation: This is because 4% of $400 is 160, and if you multiply that by 5 you get 800, then you just subtract that from the total amount and you get your final answer.
Step-by-step explanation:
Here
5x+16+7x-3+6x+5 = 180(being sum of triangle)
or, 18x=180-18
or, x= 162/18
so, x = 9
now,
here,
<ACD = <ACB(diagonals of parallelogram bisect eachother)
or, <ACD = 7x-3
or, <ACD = 7×9-3
or, <ACD = 63-3
So, <ACD = 60°
