The value of x is 22.37 and y is 20
What is Interior angle?
An angle of a polygon is formed by two sides of the polygon that share an endpoint. For a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle) if a point within the angle is in the interior of the polygon.
What is Exterior angle?
An exterior angle (also called an external angle or turning angle) is an angle formed by one side of a simple polygon and a line extended from an adjacent side.
We know, the sum of interior angle is 180 degree
The given interior angles is ,
3y + 5 and 5y + 15
So, equate to 180°
3y + 5 + 5y + 15 = 180°
Solve for 'y'
8y + 20 = 180
4(2y + 5) = 180
2y + 5 = 45
2y = 45 - 5
2y = 40
y = 20
Now, we know the sum of exterior angle is 360 degree
The given exterior angle is,
17x - 70 and 2x + 5
So, equate to 360°
17x - 70 + 2x + 5 = 360°
Now, solve for 'x'
19x - 65 = 360
19x = 360 + 65
19x = 425
x = 22.368 or 22.37
Hence, the value of x is 22.37 and y is 20
