How to do this question plz 10^27

Let S = mass of Saturn

S = 3(1.899 x 10^27)

S = 5.697 x 10^27

There is no need to work out 10 to the 27 power. The question is not asking you to do this.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
