First of, what you are referring to zeroth power is not that, actually. It is the symbol for degrees.
If the angles are complementary it means they add up to 90 degrees.
Therefore (2x+2) + (3x-5) = 90
2x + 3x +2 -5 = 90
5x - 3 = 90
5x = 90+3.
5x = 93. Divide both sides by 5.
x = 93/5 = 18.6
Therefore: (2x+2) = (2*18.6+2) = 37.2 + 2 = 39.2 degrees.
(3x- 5) = (3*18.6-3) = 55.8 - 3 = 52.8 degrees.
So the measure of the smaller anger is 39.2 degrees.
Cheers.
This is known as the visible spectrum of electromagnetic radiation, or visible light. This is the frequency of light that we see, and which illuminates our world as it reflects off of objects. Compared to the full spectrum of electromagnetic radiation, the visible light portion is actually quite small.
That means like oxygen for like breathing in your mouth
I believe the answer is B
Answer:
Based on the solar light that enters the oceans and river
Explanation:
- River ecosystem of a couple of both biotic and abiotic components among the plants and animals involving there physical and chemical properties. As the flow of water is unidirectional, it's in state of continuous physical change and has a high degree of spatial and temporal heterogeneity.
- River sources are small, and in the areas of mountain streams, are steep and erosional. In temperate environments, overhead tree canopy conditions result in cool, well-oxygenated streams.
- All sorts of communities like coastal, estuaries, reefs and deep-sea trenches like Mariana trench which has no sunlight has a distinct type of community.
