Answer:
c. wavelength
Explanation:
The wavelength is a measure of the distance between two crest. It is taken as such because it gives the horizontal separation between adjacent points on consecutive wave peaks. It is also the same as the difference between two successive troughs. A crest on a wave is the peak of the oscillation. The trough is the adjacent depression.
Climate is extremely cold and vegetation starts decreasing as a result of climate
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
