If mp = 85°, which is a possible measure for y? my = 80°my = 85°my = 100°my = 180

Given that in triangle XYZ and MPN XY=MP, YZ=PN and the ratio of XZ to MN is 23/19.

Thus the possible size of angle Y given that mP=85 will be:

mY/P=23/19

mY/85=23/19

mY=23/19*85

mY=102.9

The approximate value is therefore mY=100

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
