If triangle DEF is an isosceles triangle, angle d is the vertex angle, DE = 4x-7, EF = 3x+2 and DF = 6x- 15, find the value of x and the measure of each side

x=4, DE = 9, DF = 9, EF = 14

Step-by-step explanation:

Since D is the vertex angle, DE = DF, so that

4x - 7 = 6x - 15

-7 = 2x - 15

8 = 2x

x = 4, and

DE = 4x - 7 = 4(4) - 7 = 16 - 7 = 9

DF = 9

EF = 3(4) + 2 = 12 + 2 = 14

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.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
