2. When the central angle is 45 degrees, how can you use what you know about the Pythagorean theorem and triangles to find the sine and cosine if the radius of the circle is 1? *

a. 19,958,400

step-by-step explanation:

hope this

i really dont know

step-by-step explanation:

- 70

this is the answer for you hope it

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
