Measure of adjacent angles of parallelogram are (5 x -7)⁰ and (4 x +

1.	Measure of adjacent angles of parallelogram are (5 x -7)⁰ and (4 x + 25)⁰ find the value of x
Answer» ANSWER: Ist angle =(5x-7)° 2nd angle =(4x+25)° A/Q Ist angle +2nd angle =180 [ SUM of ADJACENT angle is 180°] (5x-7)°+(4x+25)°=180° 5x-7+4x+25=180° 9x+18=180° 9x=180°-18° 9x = 162° x=162/9 x=18° ( ans )

Measure of adjacent angles of parallelogram are (5 x -7)⁰ and (4 x + 25)⁰ find the value of x

Answer»

Ist angle =(5x-7)°

2nd angle =(4x+25)°

A/Q

Ist angle +2nd angle =180 [ SUM of ADJACENT angle

is 180°]

(5x-7)°+(4x+25)°=180°

5x-7+4x+25=180°

9x+18=180°

9x=180°-18°

9x = 162°

x=162/9

x=18° ( ans )
