Question

ABCD is a parallelogram find the value of x: If Angle A=3x-50 and angle C=x+40

Answer 1

Given: ABCD is a parallelogram if Angle A=3x-50 and angle C=x+40.

To find: The value of x.

Solution:

In a parallelogram, the opposite angles are of equal measure. In the parallelogram ABCD, A and C are opposite angles and B and D are the opposite angles. In the given question, the measure of A and C are given and they must be equated.

$3x-50 = x+40$

$2x = 90$

$x = 45$

The measure of x is found to be 45 degrees.

Therefore, the value of x is 45.

Answer 2

Answer:

Step-by-step explanation:

ABCD is a parallelogram (Given)

Value of x (To find )

3x-50° = x+40°

3x-x = 40° + 50°

2x = 90°

x = 90/2

=45 °
