Answer:
-120 degrees.
Step-by-step explanation:
This triangle has a rotational symmetry of 3 (it repeats its orientation 3 times as it makes a complete circle around the center), so the angle of rotation is 360 / 3 = 120 degrees.
As the rotation is counter clockwise strictly speaking the answer is -120 degrees.
Using the slope-intercept form, the slope of the line is 1 (Imagine there is a 1 in front of the x) and the y-intercept is -5. The answer is D.
Answer:
Height = 250km
Step-by-step explanation:
Given,
rate of rise of ballon 1 = 38 km/h
rate of rise of ballon 2 = 50 km/h
Let the time after which both the ballons will reach same height be 't'.
hence, after 't' hours,
⇒ height of ballon 1 = height of ballon 2
⇒ 38t + 60 = 50t
⇒ 12t = 60
⇒ t = 5 hours
so, the height at which both the ballons will be at the same height will be 250km.
