Answer: 9
because you need to first use the ones in the parentheses and then move on.
If ABC and DEF are complementary, then the value of x will be,
90 - ABC = x
90 - 53 = x
x = 37°
The slope formula can be used to prove a triangle has
<span>a right angle
and slope formula also prove that lines are parallel
so i conclude option B is correct

In order to get the answer you will have to divide 30 by 100 then divide the number you get from that by 20 to receive your answer.
20/x=100/30
(20/x)*x=(100/30)*x
20=3.33333333333*x
(3.33333333333) to get x
20/3.33333333333=6
=6
Therefore your answer is "6."
Hope this helps
