1.

The adjacent angles of a parallelogram are(3x - 10") and (2x + 5°), the value of xis equal to(1) 27(3) 47(4) 43(2) 37

Answer»

the awnser is the 3rd option

Answer :2)37Explanation:

In a parallelogram, opposite angles are equal. Therefore the other two angles are also 3x-10° degrees and 2x+5° degrees.

We also know sum of all the angles in any quadrilateral is 360 degrees.

Hence, 2(3x-10°) + 2(2x+5°) = 360.6x-20+4x+10=36010x=360+10x=370/10x=37

adjacent angles of parallelogram =180

(3x-10)+(2x+5) =180

3x+2x+5-10 =1805x-5=1805x=180+55x=185x=185/5x=37

The answer is 37

(3x-10)+(2x+5)=1803x-10+2x+5=1803x+2x-10+5=1805x-5=1805x=180+55x=185X=185/5X=37
