A course in the shape of a triangle consists of a running path, biking path, and skateboarding
path. The biking path is 51 meters long and the skateboarding path is 64 meters long. If the
angle between the running and biking paths is 78", find the angle between the running and
skatebording paths to the nearest tenth of a degree.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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

probably .5

i can on others if necessary.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
