Question

In the given figure, ABCD is a parallelogram. Find the value of X

Answer 1

Answer: 45°

Step-by-step explanation:

Given :-

ABCD is a parallelogram.

We know that the opposite angles of a parallelogram are equal, in this case ∠A = ∠C

∠A = (3x - 50°)

∠C = (x + 40°)

So,

→ (3x - 50°) = (x + 40°)

→ 2x = 90°

⇒ x = 45°

Answer 2

Answer:

Given fig. is a parallelogram.

We know that opposite angles of a IIgm is equal.

Therefore, ∠DAB=∠BCD

=> 3x - 50⁰ = x + 40⁰

=> 3x - x = 40⁰ + 50⁰

=> 2x = 90⁰

=> x = 90⁰/2

=> x = 45⁰ (Ans)
