Angle 1: 52 degrees
angle 2: 79 degrees
angle 3: 38 degrees
explanation:
angle 1: 180 - 90 - 38 = 52
angle 2: 180 - 63 - 38 = 79
angle 3: 90 - 52
Answer:
1.5 hr and 3.5 hr
Step-by-step explanation:
Time in the first part= x
Time in the second part= 5 - x
- 49x+60(5-x)=283.5
- 49x+300-60x=283.5
- 11x=300-283.5
- 11x= 16.5
- x= 16.5/11
- x= 1.5 hr
- and
- 5-x= 5-1.5= 3.5 hr
280 is the answer ///////////////////////////////////
Answer:
