Question

In the given figure, ABCD is a rectangle, find the value of x. Pls tell fast​

Answer 1

Answer:

REF.Image.

In Rectangle ABCD

AB=CD,AD=BC

Given that AB=13,BC=7,AD=3x+y,CD=x+y

Now,

x+y=13 __ (1)

3x+y=7__ (2)

solving (1) & (2)

x+y=13

3x+y=7

________

x−3x=13−7

⟹−2x=6

⟹−x=

2

6

⟹x=−3

Now subtitute x in eq (1)

x+y=13

⟹−3+y=13

⟹y=13+3

⟹y=16

solution

Answer 2

Answer:

120°

Step-by-step explanation:

ABCD is a rectangle

so angle CAB= angle DBA

Consider the mid point as O

We can now consider it as a triangle OAB

the total angle of a trianle is 180°

So angle AOB = 120°

Therefore it will be equal to the angle X.
