Tan 37,4 = opposite/adjacent
tan 37,4 = x/12,8
• then multiply both sides by 12,8
12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)

Using complex numbers concepts, it is found that the statement is false.
When a complex number is a root of a polynomial function, it's conjugate also has to be.
- A complex number has the format
, and it's conjugate is 
.
In this problem:
- Real root -3.
- Complex-conjugate roots 1 + i and 1 - i.
- Complex root -3 + 7i.
The conjugate of -3 + 7i also has to be a root, which would make the polynomial of the 5th degree, as it would have 5 roots, thus, the statement is false.

Answer:
18, 20 and 22.
Step-by-step explanation:
Let the lowest number be n, then:
n + n + 2 + n + 4 = 60
3n + 6 = 60
3n = 54
n = 18.
So the other 2 are 20 and 22.
39 is 65% of 60 so 60 is the number
