Answer:
137
Step-by-step explanation:
First start with what you know. The measure of the interior angles of a triangle total to 
so 51 + 2x + x = 180, then 51 + 3x = 180, 3x = 129, so
x = 43, the exterior angle is on a straight line with x so
x + exterior angle = 180 [since they are supplementary], since x = 43 then
43 + e = 180, so e has to be 137
It means that the two line segments, EF and GH, are A, parallel.
The symbol between the segments (ll) is of two parallel lines, so it's stating that the segments are parallel.
98 inches is the correct answer.
All the points on the circle
(x+1)^2 + (y-5)^2 = 2
