Correct me if i am wrong for the first one and do the second one: )

A = (a+b)/2

G = sqrt(ab)

Step-by-step explanation:

To find the arithmetic mean, we add the numbers together, then divide by how many numbers

A = (a+b)/2

To find the geometric mean, we multiply the numbers and take the nth root

G = (ab) ^ 1/2

G = sqrt(ab)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
