The value of this is -1 so the answer is B.
HOPE THIS HELPS!
HAVE A GR8 DAY;-)
3.24 + 5.70 + 6.17 = 15.11
20.00 - 15.11 = 5.11
He got 5.11$ of change back.
You would draw 48 counters and 18 counters which would be 66 counters in total. The picture is 1 of the sixteens and 1 of the nines. Sorry, if I misunderstood or got it wrong, I tried. If you don't understand something or I left out something, tell me in the comments.
X = 9
AC = AB
15 = 6 + x
15 - 6 = 9
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
