Answer:
1. Without a calendar we could not know when to celebrate any of the festivals on particular days. We would even get the days of the week confused after a while. We would not be able to tell when a year had gone by, so it would be hard to keep track of someone's age.
2. Without numbers we wouldn't be able to count or measure anything. We would forget our age one day, and possibly forget how to count. Also we wouldn't be able to tell time, unless we used the sun. It would make life very problematic.
3. It would take very long to get us somewhere. We could no longer travel with airplanes, since they use wheels to take off. Such a simple thing as going to the grocery store, would turn into a huge task. Traveling would take very long to do, or might be non-existent if we didn't use horses.
Answer:
1.bd=~ed given
2.CD=~fd given
3.<bdc=<edf
4.triangle BCD=~triangle def by s.s.a.axiom
5.BC=~ef the corresponding side of congruent triangle are equal
Explanation:
in triangle qrs &rst
- rs=~rs common side
- qr=~st midpoint bisect that side
- <qsr=<rst midpoint bisect that angle
4.traingle qrs =~rst by s.s.a.axiom
5.<rqs=<rts since the corresponding angle of congruent triangle are equal
It’s the plateau. The plateau hots several cities including la Paz.
