Step-by-step explanation:
a=5x^3
b=7y^9
that is the answer
Answer:
Speed of plane in air is 352 km/hr and speed of wind is 34 km/hr
Step-by-step explanation:
Average speed of plane in with wind = 386 km/h
Average speed of plane against wind = 318 km/hr
Consider the speed of plane in wind be x km/hr and speed of plane against wind be y km/hr
As such speed of plane in wind would be x + y km/hr and speed of plane against wind would be x - y km/hr. i.e
x+y = 386
x-y = 318
by solving these two equation, we get
2x=704
x= 352 km/hr
y=386 - 352
y= 34 km/hr
Hence, Speed of plane in air is 352 km/hr and speed of wind is 34 km/hr
Answer:
60
Step-by-step explanation:
the two angles are equal angle x and the one opposite
=180-40
=120 ÷2
=60
