I just need help with d and e but I would appreciate if my work could be checked and/or edited for a,b and c.
Answer each question as best as possible. Show all work. 8. a) Draw and label an isosceles triangle ABC with vertex angle A. B. b) Write a congruency statement identifying which sides of triangle ABC are congruent. AB=AC c) If AB = 3x + 40, AC = 5x + 10 , and BC = x + 30 , then what is BC? 3x+40 + 5xt 10 =x+30 8x+50 = x +30 7x =-20 ーメ ーメ 7x+ SU = 30 - 50 -SO d) Write a congruency statement identifying which angles of triangle ABC are congruent. e) Ifm < BCA = 4x + 10 and m < BAC = 6x + 48, then what is m <ABC?
