All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.
It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.
If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.
First, replace
and
. Then you have
If we take
, then immediately we see a differential in the numerator in the form of
. So the integral becomes
and evaluates to
making (A) the correct answer.
Answer:24
Step-by-step explanation:
18:27=16:__ let__=h
18:27=16:h
18/27=16/h
Cross multiply
18 x h=16 x 27
18h=432
Divide both sides by 18
18h/18=432/18
h=24
50.24
Explanation:
4^2
4x4=16
16x 3.14= 50.24
