Pleas help on my profile is this question of math its urgent!! i'll put 5 and the crown for the person who answere me

Find the value of x, if m< AOC = 7x – 2, m< DOC = 2x + 8, and m< EOD = 27

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
