The triangle is obtuse and the two sides of the triangle are congruent. The measure of one of the base angles is 1/6 times the difference of the vertex angle and one of its base angles. Find the measure of all three angles.

answer: the first graph

step-by-step explanation:

i would say true? if the unit was informational and it "refreshed your understanding", then true.

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.
