8 In the diagram below of isosceles triangle ABC, the measure of vertex angle B is 80°. If AC extends to point D, what is m_BCD? 50 B 80° 2) 80 IX 3) 100 A 130​

if this is really you s much. i only have 3 points left and i have 2 questions to ask

step-by-step explanation:

the answer is in the picture

vince wrote the sequence below.

1/3, 1, 5/3, 7/

the sequence is geometric because 2/3 was added to each term to get the next term.

the sequence is geometric because 3 was multiplied to each term to get the next term.

the sequence is not geometric because 2/3 was added to each term to get the next term.

the sequence is not geometric because 3 was multiplied to each term to get the next term.
