Question

In parallelogram ABCD, angle A- angle B =30 then find angle C​

Answer 1

Answer:

105 degrees

Step-by-step explanation:

in a parallelogram, sum of adjacent angles are 180 degrees so:-

angle a + angle b= 180_______(1)

and according to question

angle a- angle b= 30_______(2)

by adding equation (1) and (2),we get

2a= 210

angle a = 105

and in a parallelogram, opposite angles are equal

so, angle a = angle c

∴ angle c= 105 degrees
