Let f(x) = -1
What is the average rate of change of f(a) from 3 to 642

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

4.5%
