Which trigonometric ratios are correct for triangle def? check all that apply.

sin(d) = 24/25
cos(e) = 7/25
tan(d) = 24/7
sin(e) = 7/25
tan(d) = 7/24

According to the given right angled triangle DEF, the EF and DF are given, so we will find the unknown side ED.

ED can be found using the Pythagoras theorem.

Taking square root on both sides, we get

ED=25

1.   .... correct

2.     .... incorrect

3.   ..... correct

4.     .... correct

5.    ....incorrect

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
