Question

(P0hoto attached)

Answer 1

\[50+60+x=180\] solve for \(x\)

Answer 2

ok, the first step is to look at the 130 degrees on the left side outside the triangle. we know that the sum of 130 and the interior angle of the triangle adjacent to the 130 degree angle is 180.

130 + y = 180 // y is the interior angle.

you know that the sum of the interior angles of a triangle must sum to zero. therefore use the angle you found for y and create a new equation using y 60 and x.
