Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale. Based on these triangles, which statement about x is true?
300
x = 110, because 180 – (84 + 26) = 70 and 180 – 70 = 110
x = 238, because 180 – 26 = 154 and 154 + 84 = 238
x = 290, because 84 + 26 = 110 and 180 + 110 = 290
x = 70, because 84 + 26 = 110 and 180 – 110 = 70

In each diagram line f is parallel to line g, and line h intersects lines f and g. Based on the diagrams, which statement is true?
300
The value of x cannot be determined from the diagram.
The value of x is 75 because the two angles shown in each diagram are supplementary.
The value of x is 105 because the two angles shown in each diagram are congruent.
The value of x is less than 90 because the two angles shown in each diagram are acute angles.
