Question

find the value of x in following figure ​

Answer 1

Given:

angle BAD = 40°

angle BDC = 90°

angle ABD = x

To Find:

The value of x.

Angle Sum Property:

The sum of all the angles of a triangle is 180°.

Linear Pair:

The measure of two angles on a line is 180°.

Solution:

angle ADB = 90° = angle BDC (Linear Pair)

According to the question,

x + 40° + 90° = 180°

or, x + 130° = 180°

or, x = 180° - 130°

or, x = 50°

Answer:

The value of x is 50°.

Answer 2

☺ａｎｓｗｅｒ:

X=50°

Y=20°
