Answer 2

Answer:

x= 55 degree

Step-by-step explanation:

here, we can derive the equation,

x degree + [ 180 - 2x ] + [ 180 - 2x - 15] = 180 degree

How we derive?

here 2x and one unknown value makes an linear pair or 180 degree...

also, 2x-15 and one unknown value make linear pair or 180 degree...

so we subtract them from 180 degree

the other angles or the supplementary of exterior angles when added to x degrees make 180 degree using angle sum property......

Deriving the value:

x degree + [ 180 - 2x ] + [ 180 - 2x - 15] = 180 degree

-3x + 345 degree = 180 degree

345 degree - 180 degree = 3x

165 degree = 3x

165/3 = x

55 degree = x
