82
sinA=
82


9

and
cos
⁡
B
=
1

, and that angles
A
A and
B
B are both in Quadrant I, find the exact value of

B
)
cos(A+B), in simplest radical form

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

My math teacher told my class to "steal" a 6th grade fraction word problem from the internet, word problems? : -p requirements: only a 1 step word problem. needs to be complex.
