Answer:
30°
Step-by-step explanation:
let the first angle be x then the second angle is 2x and the third angle is
1.5 × 2x = 3x , then
x + 2x + 3x = 180
6x = 180 ( divide both sides by 6 )
x = 30
The first angle = x = 30°
Okay i get it now
1) At 1.30 p.m. the barge has already traveled 4.5 X 10 = 45 miles.
To catch up it will take the train 25-10 = 15miles
the second one is the answer hope you get a good grade on your work
7 = 1 x 7
6=2x3
8=2x2x2
LCM= 7x2x2x2x3= 8 x 21 = 168
