(4x+28)+(x+19)+(3x+13)=180
8x+60=180( combine like terms)
8x+60-60= 180-60
8x=120
8/8x=120/8
x=15
The missing angles are 88°, 34° and 58°

Answer:a)117 hours b)4.875days.
Step-by-step explanation:
Using the formula
Speed =Distance / Time
Given Distance = 3 3/5 -mile
and Speed=2/65 miles per hour.
Time =Distance / Speed
Time = (3 3/5)/(2/65)
Time =18/5÷2/65
Time =18/5 x 65/2 =117 hours
Now 24 hours =1 day
therefore 117hours =(117hours x 1 day )/ 24 =4.875days.
