Yes
That depends upont the particular desert and season of the year. The temperature could range from 60 or 70 degrees F in the southwest American deserts in summer to well below minus 100 degrees F in Antarctica in winter.
SOMETIMES. It could be 60 degrees, 60 degrees, and 60 degrees which is an equilateral triangle and also an acute triangle. It can ALSO be isosceles. 50 degrees, 50 degrees, and 80 degrees. And of course it could be scalene.
Every desert has its own statistics so you need to be specific. The temperature could range from -129 degrees F. in Antactica to +134 degrees in Death Valley.
Each desert has its statistics and temperatures can vary from desert to desert. Temperatures in the Antarctic Desert can plunge to over 100 degrees F. below zero or be has high as 140 degrees F. above zero in the Sahara or Mojave Desert.
60 degrees Celsius is warmer than 60 degrees Fahrenheit. 60 degrees Celsius is equivalent to 140 degrees Fahrenheit.
isosceles * * * * * In the Euclidean plane such a triangle could not exist, because the sum of its angles exceeds 180 degrees.
Every desert has its own weather statistics. There are hot deserts and there are cold deserts. In the Antarctic Desert the temperature may plunge below -100 degrees F. In hot deserts during the summer the temperature may drop below 60 degrees F. at night.
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
Desert biomes can be found around the world at various latitudes and longitudes. Some examples include the Sahara Desert in Africa (approximately between 20-30 degrees North latitude and 0-20 degrees East longitude), the Arabian Desert in the Middle East (around 20-30 degrees North latitude and 40-60 degrees East longitude), and the Sonoran Desert in North America (around 30-35 degrees North latitude and 110-115 degrees West longitude).
