Question

find the value of x by using properties​

Answer 1

Here , the property to be used :

Sum of all the angles of a quadrilateral = 360°.

Given angles are of magnitude = 56°, 90°, x and x

To Find : the value of x

Solution :

56°+90°+x+x = 360°

156° + 2x = 360°

2x = 214°

x = 107°

The required value of x = 107°.

Answer 2

$\huge\mathfrak\red{Answer}$

We can apply {Angle sum property}That sum of any triangle is 180°.

so 1st we have to divide it into 2 parts.

And we can see in the figure ( A ) it makes a 90° angle.

so A is 90°.

Bisecting from D and B
