What is the measure of ABC?

Using exterior angle theorem, we can find the answer.

x+45+3x = 6x+5

4x+45 = 6x+5

45 = 2x+5

40 = 2x

x = 20

TO FIND <ABC, WE WILL NEED TO FIRST FIND THE EXTERIOR ANGLE.

6x+5

= 6(20)+5

= 120+5

= 125

m<ABC:

180-125               (REASON: linear pair)

= 55

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
