Answer:
x = 77°
Step-by-step explanation:
A flat angle is 180°.
180° - 130° = 50°
The sum of all the angles in a triangle is 180°.
180° - 50° - 53° = 77°
77°
name the third side of the triangle y
therfore we look for y first
y=180-130(angle on a straight line is 180)
=50
now we find x
as well know the sum of angle in a triangle is 180
x=180-(53+50)
=180-103
x=77°
