Parallelograms/750492: Parallelogram ABCD has obtuse angles that are twice as big as the acute angles. What is the measurement of each acute angle? 1 solutions Answer 456614 by jim_thompson5910(28598)   on 2013-05-19 18:05:02 (Show Source): You can put this solution on YOUR website! Let x = measure of acute angle, so 2x is the obtuse angle (since it's twice as big). Adjacent angles in a parallelogram add to 180 degrees, so we can say x + 2x = 180 ... now solve for x 3x = 180 x = 180/3 x = 60 2x = 2*60 x = 120 So the obtuse angles are 120 degrees and the acute angles are 60 degrees

Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is Since this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis So we have one point Now since the slope is comprised of the "rise" over the "run" this means Also, because the slope is , this means: which shows us that the rise is 1 and the run is 1. This means that to go from point to point, we can go up 1 and over 1 So starting at , go up 1 unit and to the right 1 unit to get to the next point Now draw a line through these points to graph So this is the graph of through the points and

Exponents/750483: multiply this problem (2a+2)^3= 1 solutions Answer 456596 by jim_thompson5910(28598)   on 2013-05-19 17:33:37 (Show Source): You can put this solution on YOUR website! (2a+2)^3 = (2a+2)(2a+2)(2a+2) (2a+2)^3 = (2a+2)(4a^2 + 8a + 4) (2a+2)^3 = 2a(4a^2 + 8a + 4) + 2(4a^2 + 8a + 4) (2a+2)^3 = 8a^3 + 16a^2 + 8a + 8a^2 + 16a + 8 (2a+2)^3 = 8a^3 + 24a^2 + 24a + 8
