Let us rewrite this equation as:
<em>160/x = some number + 4/x
</em>we can assume that some number of x's can fit into 160, but x is greater than 4 so we have a remainder.
We can figure out by using the remainder that x is completely divisible into (160-4) or 156. Knowing this we can assume that x is some factor of 156 that is greater than 4.
Let us list the factors of 156
1,2,3,4,6,12,13,26,39,52,78,156
Now let us refer back to the restrictions we put on x.
<em>x must be > 4 as anything less than 4 would divide at least 1 more time into it. So now we are left with a bunch of other factors. And the cool thing is that all of the factors excluding anything that is = or < 4 all work for getting a remainder of 4. Thus we can use the largest factor and set it equal to x.
</em>So x = 156
then if we divide 315 by x or <em>315/x = 315/156 = 2 and a remainder of 3
so the answer would be 3.</em>
Some parallelograms have 2 obtuse and 2 acute angles.
Parallelograms may have all 90 degree angles as well. These are also called rectangles.
When you "bend" a rectangle it naturally forms 2 acute and 2 obtuse angles.
1. can't be determined cause no info given on the rate of which the population is growing.
2. can't be determined/not true because the initial population of a could be less than b.
3. can't be determined/not true because we don't have enough info to tell how fast they grow and decline.
Answer:
100°
Step-by-step explanation:
the total of all angles around O on one side of AD is 180° (as that would represent a half-circle).
and the sum of the arc angles AB + BC + CD covers the whole 180°.
so, we have
180 = 55 + BC + 25
180 = 80 + BC
BC = 100°
5578/68=82.029411764705882352941176470588
that would be rounded to 82.02 which is the answer
