If angle abd=79 what are angles abc and dbc
abc=5x+4
dbc=8x-3

Step-by-step explanation:

I believe this is geometry,

One exterior angle = sum of two opposite interior angles

ABC + DBC = ABD

5x + 4 +(8x-3) = 79

5x +4 + 8x - 3 =79

13x + 4 - 3 =79

13x + 1 = 79

13x = 79-1

13x = 78

x = 78/13

x = 6

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

50-60=10
