Answer:

121

Step-by-step explanation:

First we find angles of triangle:

First angle is: 180-115=65

Secend angle is:360-304=56

Sum of all angles in triangle is 180. So the 3th angle of triangle is:

180-(65+56)=180-121=59

Sum of x and 3th angle is 180, then

X=180-59=121

Step-by-step explanation:

<ABC +<ABE = 180°(straight angle)

<ABC = 180-115° = 65°

<A = 360°-304° = 56° ( complete angle)

external angle of a triangle is equal to the sum of two opposite interior angles.

therefore, x = 56°+65°= 121°
