Lesson 2

Find a if AB = 4a + 10, BC = 3a – 5, and AC = 19.

C. Find x and SU if T is between S and U, ST = 7x, TU = 42, and TU = 5x – 3.

Slide 1 4 planes: Planes Y or FGD, EGD, EGF, and EFD Points A, B, C are collinear because the all share the

same line Points A, G, D, and E (or A or C) are non-coplanar

because E is not in the plane with A, G, and D. Line AC
