Aplane traveling 500 mph (called airspeed) in the direction 120 degrees encounters a wind of 80 mph in the direction of 45 degrees

what is the resultant direction of the plane (in degrees)?

a. 78.9
b. 111.6
c. 113.8
d.cannot determine from information given.

The property used here is:

Commutative property of addition

Step-by-step explanation:

Commutative property of addition states that if a and b are any two elements

then, a + b = b + a

We are given a equality we have to determine the property used here

5x · (4y + 3x) = 5x · (3x + 4y)

In the above equation, 4y + 3x = 3x + 4y

a= 4y and b= 3x

Then, a+b=b+a

Hence, the property used above is:

Commutative property of addition
