The required value of the exterior angle x = 155°
A figure of angle in triangles is shown in which the value of x is to be determined.
What is the angle?
The angle can be defined as the one line inclined over another line.
From the image attached below From the orange triangle,
The sum of the interior angle of a triangle is 180°,
35 + 90 + z =180
z = 180 -90 - 35
z = 55
Now, the sum of the angle
z + y + 60 = 180
55 + y + 60 = 180
y = 180 -60 - 55
y = 65
Now angle x can be given as the sum of the remote angle is equal to exterior angle x.
35 + z + y = x
35 + 55 + 65 = x
x = 155
Thus, the required value of the exterior angle x = 155°
