Answer:
120
Step-by-step explanation:
Angles opposite to equal sides are equal .
30 + 30 + x = 180 {Angle sum property of triangle}
60 + x = 180
x = 180 - 60
x = 120
Given:


To find:
The obtuse angle between the given pair of straight lines.
Solution:
The slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
The given equations are


On comparing these equations with (i), we get


Angle between two lines whose slopes are
is

Putting
and
, we get



Now,
and 
and 
and 
, so it is an obtuse angle and
, so it is an acute angle.
Therefore, the obtuse angle between the given pair of straight lines is 120°.
