The sum of two opposite angles of a parallelogram is 130 find all the angles of the parallelogram
so those opposite angles are 130/2 = 65
sum of all the angles is 360
so 130 + 2 theta = 360
theta = 115
so two angles of 65 deg and two angles of 115 degrees
To find all the angles of a parallelogram, we need to know that opposite angles in a parallelogram are equal. So, if the sum of two opposite angles is 130 degrees, we can divide it by 2 to find the measure of each opposite angle.
Let's say one of the opposite angles is x degrees. Since the sum of two opposite angles is 130, the other opposite angle would also be x degrees. We can write this as an equation:
x + x = 130
Combining like terms, we get:
2x = 130
To solve for x, divide both sides of the equation by 2:
x = 130/2
x = 65
Therefore, each opposite angle of the parallelogram would measure 65 degrees. Since opposite angles are equal in a parallelogram, all the angles of the parallelogram would be 65 degrees.
Your right answer
sum of the four angles =(4-2)
sum of the two angle =360-130=230
so,
second angle = 180/2=65 degree
second angle = 210/2=115 degree
Sum of all the angles is 360
So 140+2=360
=142
