Answer:
Therefore values of a and b are
Step-by-step explanation:
Rewrite in the form
where a and b are integers,
To Find:
a = ?
b = ?
Solution:
..............Given
Which can be written as
Adding half coefficient of X square on both the side we get
...................( 1 )
By identity we have (A - B)² =A² - 2AB + B²
Therefore,
Substituting in equation 1 we get
Which is in the form of
On comparing we get
a = 3 and b = 2
Therefore values of a and b are
The angle A=180-37=143 degrees
and the angle B is equal to the angle A because l and m are parallel line then B=143 degrees
angles C and D are equal to A and B too, then C=D=143 degrees
angles G, E and F are equal to the given angle because they are opposite by the vertex and alternal internal, then G=E=F=37 degrees
