4. The angles of a quadrilateral are (2x + 4),(2x - 1), (2x + 5)°, 2(3x + 2)°, respectively,
Find the value of x.
Answers
The value of x is 29.
Given:
The angles of the quadrilateral are (2x + 4)°, (2x - 1)°, (2x + 5)° and 2(3x + 2)°.
To find:
The value of x
Solution:
According to the Angle Sum Property of the triangle, the sum of all the interior angles of a triangle is equal to 360°.
According to the given data, the four angles of the given quadrilateral are (2x + 4)°, (2x - 1)°, (2x + 5)° and 2(3x + 2)°.
Applying the Angle Sum property to the given quadrilateral,
(2x + 4)° + (2x - 1)° + (2x + 5)° + 2(3x + 2)° = 360°
=> 2x + 4 + 2x - 1 + 2x + 5 + 6x + 4 = 360
=> 12x + 12 = 360
=> x + 1 = 360 / 12
=> x = 30 - 1
=> x = 29
Hence, the value of x is 29.

The value of x is 29
GIVEN:- (2x + 4),(2x - 1), (2x + 5)°, 2(3x + 2)°
TO FIND:- the value of x
SOLUTION:-
According to the question we are given a quadrilateral
As we know that the sum of all the angles of a quadrilateral is 360°
Thus, the sum of all the given angles = 360°
Dividing both sides by 12
Hence, the value of x is 29
