Question

in fig 1 what value of x will make PQR a straight line ​

Answer 1

HEY MATE

HERE IS YOUR ANSWER

angle PQR = < PQM + < MQN + <NQR

180 ° = 30 + 2x + x........ linear pair

180 ° = 30 + 3x

180 ° - 30 = 3x

3x = 150

x = 150/3

x = 50

HOPE IT HELPS

HAVE A NICE DAY AHEAD....^ _ ^

Answer 2

angle PQM=30

angle MQN=2x

angle RQN=x

30+2x+x=180 [angle in straight line]

30+3x=180

3x=180-30

x=150/3
x=50
