For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:

(5x + 12) + (6x + 30) + (2x + 8) = 180\\5x + 12 + 6x + 30 + 2x + 8 = 180

We add similar terms:

13x + 50 = 180\\13x = 180-50\\13x = 130\\x = \frac {130} {13}\\x = 10

Answer:

x = 10

What is the measure of the highlighted angle
IgorLugansk [536]
Angle on a straight line sums up to 180
so
72+x + x+130 = 180
2x = 180-72-130
2x =-22
x= -11

so Angle on the LHS is 61°
while angle on the RHS is 119°
