Question

Find the value of x and y in the
following parallelogram
-:
B
100 + x
Y
140 - X
Y
C С
D​

Answer 1

Answer:

Answer:

there is voltage change when current through a circuit changes as u know that voltage is current cross resistance so its simple that resistance is constant but current changes cases voltage change ?

Answer 2

Answer:

x=20° and y=60°

Step-by-step explanation:

In the parallelogram the opposite angles are equal

so ∠C=∠A

140-x=100+x

2x=140-100

2x=40

x=20

Thus

∠C =140-x=140-20=120°

Now ∠C+∠D=180°

120+y=180

y=180-120=60°
