What is the exterior angle?

The value of x° is 22° and exterior angle is 25.

Step-by-step explanation:

l can prove like this,

Here,2x°+(103-x)°=(6x-7)°...Being exterior angle

or,2x°+103°-x°=6x°-7°

or,x°+103°=6x°-7°

or,103°+7°=6x°-7°

or,5x°=110°

or,x°=110°÷5=22°

Now,

x°=22°

(6x-7)°=(6×22-7)°=125°

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
