Ray su is an angle bisector of ∠rst. the measure of ∠tsu is 42°. what is the measure of ∠rsu? 90° 84° 42° 168°

How do you determine whether a relationship represented as as graph is linear or nonlinear

Factor and solve to find roots x squared -x - 90 =0

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
