7. More Lessons 4 & 5 If two angles are supplementary and the measure of one angle is 5 more than 4 times the other, what are the measures of the angles? If angles 1 & 2 are complementary and angle 2 is 10 more than 3 times angle 1, what is the measure of each If two angles form a linear pair and they are congruent then what are the measures of the angles? If two angles are supplementary and one angle is equal to half the other angle plus 18, what are the measures of the angles?

8. Answers 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

9. Answers Slide 2  a = 2  x = 9, SU = 105

10. Answers Slide 3  (2, 5)  2 (-6, -3)  AH = 16 DB = 5  Mdpt of CE = 0 mdpt of GA = -3/2

11. Answers Slide 4  Angles AGC and FGD  Angles AGF and CGD  Angles AGF and FGD/AGC Angles AGB and BGD Angles CGD and ACG/DGF  Angles BGC and CGD  3x-8=x+24, x=16, angle AGF=40  45 degrees each

12. Answers Slide 5  5+4x+x=180 5+5x=180, x= 35, angles= 35 and 145  X+3x+10= 90 4x+10=90, x=20, angles = 20 and 70  90 degrees each  x+ 1/2x +18=180 3/2x +18=180, x=108, angles = 108 and 72
