A E T Geo CP 2-1 Day 1 If AT = 10, EA = 2x + 5 and ET = 23, what is x? Postulate (Formula) EA + AT = ET Substitute (2x + 5) + 10 = 23 Simplify 2x + 15 = 23 Solve 2x = 8 x = 4
A G P Geo CP 2-1 Day 1 If GP = 13, AP = 2x + 5 and AG = 3x - 2, what is AP? Postulate (Formula) GA + AP = GP Substitute (2x + 5) + (3x – 2) = 13 Simplify 5x + 3 = 13 Solve for x, then substitute x into AP.
