Direction: In each of the following questions, a statement of Asserti...
2x + 3x + 7x + 6x = 360º
=> 18x = 360º
=> x = 360º/18 = 20º
First angle = 2 × 20º = 40º
Second angle = 3 × 20º = 60º
Third angle = 7 x 20º = 140º
Fourth angle = 6 x 20º = 120º

Direction: In each of the following questions, a statement of Asserti...
Assertion: If the angles of a quadrilateral are in the ratio 2 : 3 : 7 : 6, then the measure of angles are 40º, 60º, 140º, 120º, respectively.

Reason: The sum of the angles of a quadrilateral is 360º.

Explanation:
To determine the measure of angles in a quadrilateral, we need to understand the concept of the sum of angles in a quadrilateral.

Sum of angles in a quadrilateral:
The sum of angles in a quadrilateral is always equal to 360 degrees. This is a well-known property of a quadrilateral.

Explanation of the assertion:
When the angles of a quadrilateral are in the ratio of 2 : 3 : 7 : 6, we can represent these angles as 2x, 3x, 7x, and 6x, respectively, where x is a constant.

According to the assertion, the angles are in the ratio 2 : 3 : 7 : 6. Let's calculate the total sum of these angles:

Sum of angles = 2x + 3x + 7x + 6x = 18x

To find the value of x, we need to equate the sum of angles to 360 degrees:

18x = 360
x = 360 / 18
x = 20

Now, we can substitute the value of x in the angles:

Angle 1 = 2x = 2 * 20 = 40 degrees
Angle 2 = 3x = 3 * 20 = 60 degrees
Angle 3 = 7x = 7 * 20 = 140 degrees
Angle 4 = 6x = 6 * 20 = 120 degrees

Therefore, the measure of angles in the quadrilateral is 40º, 60º, 140º, and 120º, respectively.

Explanation of the reason:
The reason provided is the well-known property that the sum of angles in a quadrilateral is always equal to 360 degrees.

Conclusion:
From the above explanation, we can conclude that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
