Question

class 7 th maths exercise 5.2.
4 th question Findthe value............if l||m​

Answer 1

Answer:   answer of 1 question is x = 110 and answer of second is x = 100

Step-by-step

1. 110 degree is corresponding to left side of angle x and so if we subtract 180 from 110 then answer will be 70  so left side is 70 degree then we know that left side of that angle and x side = 180 degree so to find value of x we have to subtract 70 from 180 and the vale comes out is 110 degree.

so x = 110 degree

2. x = 100 because 80 degree angle is corresponding  with another part of x as x + it,s right side = 180 degree

so if we subtract 100 from 80 then it wil be hundred

x = 100

Hope it will help..... :)
