Question

in a parallelogram ABCD,∆A=100°∆B=80°,∆D=75 step by step explain​

Answer 1

Answer:

The value of the angle C is 105°

Step-by-step explanation:

we know that the sum of the angle of a parallelogram is 360°

so

angle A+ angle B +angle C+ angle D=360°

=100°+80°+C+75°=360°

=>255°+C=360°

=>C=360°-255°

=105°
