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:
It's the Best answer B
Step-by-step explanation:
Because yes is línea test
You no understand put the B answer friend
Answer:
graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.
Step-by-step explanation:
First simplify. 2x+3y= -18., -----------> 3y= -2x -18., ---------> y= -2/3x -6
To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.
