A student wants to prove that the base angles of an isosceles triangle are congruent. The student draws isosceles triangle ABC with base angles B and C. Point M is drawn as the midpoint of BC.

Which of the following could be used as part of the proof that B = C? Select all that apply

BM=CM bc of the definition of midpoint

AB =AC bc of the def of an isosceles triangle

and angle B = angle D becasur corresponding parts

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
