M(x, y) = ((x1 + x2)/2, (y1 + y2)/2) = ((-2 + 4)/2, (5 - 9)/2) = (2/2, -4/2) = (1, -2)
Use the slopeformula 3 times and you should found the pair
4.65
13 ÷ 20 is 0.65, just add the 4
Step-by-step explanation:
All the sides of the triangle are equal
Therefore, it is a equilateral triangle
and all angles measure 60°.
So, 25x-15= 60
25x = 60+15= 75
x= 75/25
x= 3
2y = 60
y=30
