The base of the wedge is a horizontal rectangle measuring 60cm by 40cm

17.1 degrees

Step-by-step explanation:

The complete question in the attached figure

step 1

Find the length side of the diagonal AC in rectangle ABCD

Applying the Pythagorean Theorem

substitute the given values

step 2

Find the length side RC in the right triangle BRC

we know that

----> by TOA (opposite side divided by adjacent side)

substitute the given values

step 3

Calculate the angle that AR makes with the horizontal plane ABCD

In the right triangle ARC

we know that

----> by TOA (opposite side divided by adjacent side)

substitute the given values

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.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
