Arhombus of sides 20cm han an angled of 60degree, find the lenghts of its diagonals

20 cm and 34.64 cm.

Step-by-step explanation:

Consider the triangle with vertex 60 degrees. The diagonal is perpendicular to the other diagonal , and  it bisects the  60 degree angle.

So we have the relation  cos 30 = x / 20 where x = 1/2 of the diagonal.

x = 20 cos 30

x = 17.32

And as the diagonals bisect each other this diagonal = 2*17.32 = 34.64 cm.

Similarly, the other diagonal = 2 * 20 cos 60 =  20 cm

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.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
