If it is 3kg, it will be:
40mins x 3 = 120mins
Add the extra 20 mins, it will be 140 mins. This equates to two hours and 20 minutes.
Since angle A = Angle B, I believe you would write it out like this:
6x+12=3x+63
subtract 3x from both sides, then subtract 12 from both sides.
3x=51
divide 51 by 3 to find x.
x=17
Now to find the measure of angle A.
A = 6(17)+12
A = 102+12
A = 114, angle A is 114 degrees.
If you look at the figure, you will see that there is an angle opposite each angle whose value we have. Therefore, just do (3x+2x+x)·2= 6x·2=12x
Now, 360/12=30°
x=30°
