It is true that the rainfall that happens in savannas especially in summer time reaches to only half of the annual rainfall. Isolated trees and some types of shrubs are found in savanna. The precipitation rate received by savannas per year is about 30 to 50 inches.
An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way

The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources

- Overlapping of ranges takes place to the organism and old and new species are living i the same geographical region.
- A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.
