⇒ 3(2cd - ab) = 1

⇒ 2cd - ab = 1/3

another equation is,

ab - 2cd = p

⇒ -1(2cd - ab)= p

⇒ -1/3 = p (putting the value of 2cd - ab)

Ans: P = -1/3

A. 60, 60, 60
B. 30, 60, 90
C. 60, 120, 120
D. 60, 120, 150

View Answer	Favorite Question

Answer: Option C

Explanation:

Opposite angles of a parallelogram are equal. So, the angle opposite to 60° is also 60°.

Now, sum of the 4 angles is 360°. So, sum of the other two opposite angles is {360 - (60 + 60)} = 360 - 120 = 240°

So, each of the other angles is = 240/2 = 120°.

So, the other three angles are 60°, 120°, 120°.
