5. We can see that angle a is the same angle as the 130° angle, since they form a Z. The same goes for b and 65°. a° = 130°, b° = 65°
6. With the same Z angles, b° = 56°. Because the angles are parallel, a° = 124°
7. Because the angles are parallel, b° = 83°, and a° = 132°
8. Because the angles are Z angles, a° = 74°. Because a° and b° are supplementary angles, b° = 180° - 74° = 106°. Because c° and 74° are supplementary angles, c° = 180° - 74° = 106°. Because d° and 65° are parallel angles, d° = 65°. Because d° and e° are opposite angles, e° = 65°
1.2+d+0.4=9.7
1.6+d=9.7
-1.6. -1.6
D=8.1
Try 3.14x2= 6.28 im so sorry if its wrong
18 by 12
because 6*3=18 and then 4*3=12 so this is your answer
Another word for elasticity is also called D: responsiveness
