Answer:
ear
Step-by-step explanation:
Answer:
c=sqrt21
Step-by-step explanation:
angle c is the angle between a and b, so use the cos law
c^2=a^2+b^2-2*a*b*cosC
c^2= 16+25-2*4*5*1/2
c^2=21
c=sqrt21
Answer:

Step-by-step explanation:
From the question we are told that
Angle 
Height of plane 
Generally the equation for the total distance flown is mathematically given by


Therefore total distance flown is

To make the pattern it only uses a horizontal translation and a 180 rotation, so the second one.
Hope this helps.
