Answer: 75
This is how I did it: We know that triangles add up to 180, so subtract the known angle from 180 and you'll get 150. Then divide 150 by 2 to find out the other two angles and you'll get 75.
180-30=150
150÷2=75
So the answer is 75

Human activities affect the operation of physical environment processes, and the results rebound on the human world. ... The physical environment provides resources and a platform to use those resources, but can also be a hazard to people. Therefore human impact as a subject is of special concern to physical geographers.

Answer:
The most recent eon is subdivided into three eras and eleven periods.
Explanation:
The geological time scale has been constructed so that it can help in better research and understanding of the past, as well as making it easier to distinguish the past and its characteristics at a certain time. There are larger and smaller divisions in the geologic time scale, with the eon being the largest unit, followed by era, and then period.
The most recent eon is the Paherozoic, starting from 542 million years ago and still going on. It is subdivided into three eras and eleven periods so far. The three eras are:
- Paleozoic
- Mesozoic
- Cenozoic
The eleven periods are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian
- Triassic
- Jurassic
- Cretaceous
- Tertiary
- Quaternary
