Two adjacent angles of a parallelogram are (3x-4)° and (3x+10)°.Find the angles of parallelogram.
Answers
3x-4+3x+10=180
6x+6=180
6x=180-6
x=174/6
x=29
therefor 1st angle=3*29-4=83
2nd angle=3*29+10=97
Given,
Two adjacent angles of a parallelogram are (3x-4)° and (3x+10)°
To find,
The angles of the parallelogram.
Solution,
We can simply solve this mathematical problem using the following process:
As per mensuration;
Any two adjacent angles of a parallelogram are supplementary. {Statement-1}
And, opposite angles of a parallelogram are equal.
{Statement-2}
Now, according to the question;
(3x-4)° + (3x+10)° = 180°
(3x-4)° + (3x+10)° = 180°{according to statement-1}
=> 6x + 6 = 180
=> x + 1 = 30
=> x = 29
Now, the two adjacent angles of the given parallelogram are:
the two adjacent angles of the given parallelogram are:(3x-4)° and (3x+10)°
=> (3×29 - 4)° and (3×29 + 10)°
=> 83° and 97°
Now, according to statement-2, as opposite angles are equal, so out of the 4 angles of the parallelogram, 1 pair of opposite angles measure 97° and the other pair of opposite angles measure 83°, respectively.
Hence, the four angles of the parallelogram are 97°, 83°, 97°, and 83°, respectively.
