CBSE Class 9 Answered

in the given figure, what value of x will make POQ a straight line
Asked by Prashanth Balasubramaniam | 13 Oct, 2012, 10:47: AM
answered-by-expert Expert Answer

For POQ to be a straight line , we have

?POR + ?QOR = 1800

Given that ?POR = 4x-36 and ?QOR = 3x-20

Therefore, we get

4x - 36 + 3x - 20 = 180

7x - 56 = 180

7x = 236

x= 33.70

Therefore, POQ will be a straight line if x = 33.70
