1 . a plane flies 120 km on a bearing of 045° and then flies due east. how far east of the starting point is the plane ? 2. an aircraft flies due north from airport x to y and then flies due west to z. if y is equidistant from x and z. calculate the bearing of of x from y

plsss with the whole procedure pls the two questions and i will give a brainliest ​

In my sketch the angle between their flights is 135°

So wouldn't we just have the cosine law??

x^2 = 120^2 + 150^2 - 2(120)(150)cos135°

carry on, take care with the cos135, since it will be negative

Step-by-step explanation:

I hope this helped , have a great day :)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
