Answer:Step-by-step explanation:a= 70 degreeb= x degreec= x degreed= x degreethen value of all three angle = x+x+x =3xvalue of all four angle=360 degree3x=360 x=360/3x=120 degree120-10= 110 degree.The sum of the angles of a parallelogram is 360 degrees. At least two angles will be the same unless one angle is of measure 90 degrees (in which case all four are 90). Hence, the remaining angles are 70 degrees and 2 110 degree angles.

Question:

Parallelogram ABCD ∠ A = 70o . Find all other angles

To Find:

Find all other angles

Solution:

A=70 digree

B=x digree

C=x digree

D=x digree

Then value of all three angles=x+x+x+

=3x

Value of all four angles =360 digree

3x=360

X=360/3

X=120 digree

120-10=110

The sum of the angels of a Parallelogram

360 digree. At least 2 angles will be same unless one is of angle measures 90 digrees (in which case all 4 are 90.) Hence, the remaining angles are 70 degrees and 2 ,110 degree angles.
