Question

. 13)ABCD is a parallelogram. What is the value of x?
D= 2x+40°
B= 60°​

Answer 1

Answer:

answer is X=40/2

X= 20

Step-by-step explanation:

this is the answer

Answer 2

Answer:

x = 10 degree

Step-by-step explanation:

Here, angle B = angle A (corresponding angles)

Also, angle A = angle D (alternate interior angles)

thus, angle B = angle D

so,

$2x +{40}^{0} = {60}^{0}$

$x = {10}^{0} or \: x \: = 10 \: degree$
