105 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
50 degrees if its a triangle
150 degrees
1st angle = 30 degrees 2nd angle = 60 degrees
X=30 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
30 degrees
An angle with 30 degrees is an acute angle.
90 - 30 = 60 degrees.
50 degrees if its a triangle
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
The complement of any angle is the angle which adds to it to make 90 degrees. In this instance, an angle of 60 degrees adds to 30 to make 90 degrees. Therefore, the complement of 30 degrees is 60 degrees.
It is 60 degrees
150 degrees
In parallelogram ABCD, angle A and angle D are adjacent or consecutive angles and are supplementary, meaning the sum of their measures is equal to 180 degrees. Angles A and C are opposite angles and have the same measure. These are some important properties of parallelograms. So to find the measure of angle C, you first have to find the measure of angle A. You can do that with a little algebra. First, set the expressions for the measures of angles A and D equal to 180 and solve for x. Then plug that value for x into the expression for the measure of angle A, which is the same as the measure for angle C. 5x + 30 + x = 180 6x + 30 = 180 6x = 150 x = 25 Therefore, 5x + 30 = 5(25) + 30 = 125 + 30 = 155 The measure of angle C is 155.
90 - 30 = 60 degrees.
