Let "what" and "what" be A and B
Put this in an algebraic equation
A * B = 21
A + B = -22
A must = -21 and B must = -1 , this is because two negatives multiply to make a positive
A + B = -22 , -21 +-1 = -22
<span>let the angles be x and y.
as they are compliment
x+y=90
also given
x=7y
substituting value of x in first equation
7y+y=90
8y=90
therefore
y=11.25
x=7*y=78.75</span>
For the first one I believe that the numbers are both odd and I am not sure about the second one sorry
3,345 divided by 18 is 185.8333....The three goes on forever.
Steps:
Does 18 go into 3? No
Does 18 go into 33? Yes
How many times? 1
33-18= 15, and then you would bring down and keep doing what I did. Hope this helped!
