Question

Triangle ABC is Isosceles with vertex B. If m 10 years ago

Answer 1

yeah

Answer 2

Hmm, I got 87 for <A and 62 for <C

Answer 3

I setted them like 3x-6+2x+x=180

Answer 4

well, first we notice it's isosceles so 2 sides are equal

Answer 5

right

Answer 6

3X-6+3X-6+2X=180

Answer 7

8X-12=180
8x=192
x=24

Answer 8

Thats what I got and <A = 66 and <C = 66, so B must be 48

Answer 9

ye

Answer 10

Actually hold on, my teacher told me to set <A and <C into each other since we are dealing with two congruent sides and we take that x and find the measure of <A and <C and then subtract 180 with those two combined and find <B..But i got 144 for <B so why is there no two congruent measures?
