You hike 400 feet up a steep hill that has a 25 degrees angle of elevation as shown in the diagram. Give each side and angle measure rounded to the nearest whole number.

a.) 48m

b.) 158m

m<B.) 73 degrees

Step-by-step explanation:

9514 1404 393

  a = 169 ft, b = 363 ft, B = 65°

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you remember the necessary trig relations. For side 'a', opposite the given angle A, the appropriate relation is ...

   Sin = Opposite/Hypotenuse

  a = (400 ft)sin(25°) ≈ 169 ft

For side 'b', adjacent to the given angle, the appropriate relation is ...

  Cos = Adjacent/Hypotenuse

  b = (400 ft)cos(25°) ≈ 363 ft

Of course angle B is the complement of angle A:

  B = 90° -25° = 65°

__

In summary, ...

  (a, b, A) = (169 ft, 363 ft, 65°)

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
