Answer 1

Answer:

In a parallelogram, opposite angles are equal

⇒∠A=∠C⇒2x+50=3x+40⇒x=10



Answer 2

Answer:

w.k.t : Opposite angles of a parallelogram are equal

therefore, (3x - 50) = (x plus 40)

now, solve for x

Step-by-step explanation:

3x - 50 = x plus 40

3x - x = 40 plus 50

2x = 90

x = 45°. <answer>

p.s. my (plus) sign was not coming up so had to write like that, sorry, plz bear with that..

hope your question got solved!
