Answer:
Vertices are basically the point where 2 sides meet. In this shape the vertices are:
A, B and C
The sides are;
AB. BC, and CA
The angles are all 60°, this is because it is an equilateral triangle (all the sides seems to be equal)
n=-2 over 1m plus 45. Rise over run is the 2 over one and 10 plus 45 is 55
don't forget to make me the brainiest.
D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50
x÷y=50
Do 9+4 because you need to get m alone. you get 13 plug 13 in for m (13-4=9) and then 9=9
