Step-by-step explanation:
Get a line of which you want to know the slope.
Pick any two coordinates that the line goes through.
Subtract the two y-coordinates from one another.
Subtract the two x-coordinates from one another.
Angle 2 is half of 115 so it would be 57.5 and angle 1 would be 122.5 degrees
Answer:
77
Step-by-step explanation:
85-69=16
16/2=8
69+8=77
Since the question is asking for the time units to be in hours, you want to convert 30 minutes to an hour; 0.5
We’re able to use the basic motion formula for velocity to work out this question.
Velocity = distance / time
Velocity = 5 / 0.5
Velocity = 10km/h
Therefore, Stanley’s average speed was 10 kilometres per hour. :)
You will notice that 48°, x, and x lie upon a straight line. The sum of those angles must then be equal to 180°. Which means:
48+x+x=180
48+2x=180
2x=132
x=66°
