In a provided parallelogram, the measure up of among the inner angles is 25 levels less than another. What is the approximate measure up rounded to the nearest degree of the larger angle?
Explanation:
There space two contents to resolving this geometry puzzle. First, one have to be aware that the amount of the steps of the interior angles of a parallelogram is 360 levels (sum that the interior angles the a figure = 180(n-2), wherein n is the variety of sides that the figure). Second, one must understand that the various other two inner angles space doubles of those given here. For this reason if we assign one internal angle as x and also the various other as x-25, we uncover that x + x + (x-25) + (x-25) = 360. Combining favor terms leader to the equation 4x-50=360. Solving for x we uncover that x = 410/4, 102.5, or around 103 degrees. Since x is the measure up of the larger angle, this is our answer.
