Answer:
the coordinates of the centroid of the triangle with the vertices A(-6,8), B(-3,1),andC(0,3).
={(-6-3-0)/3,(8+1+3)/3}=(-<em>3</em><em>,</em><em>4</em><em>)</em>
<em>( - 3, 4 ) </em>
Step-by-step explanation:
The centroid of a triangle is the intersection of the three medians of the triangle.
A ( - 6, 8 )
C ( 0, 3 )
Coordinates of the midpoint of AC are D( - 3, 5.5 )
Median BD is x = - 3
Coordinates of midpoint of BC are E( - 1.5, 2 )
= -
Equation of median AE is y = - x
Solve system of equations:
y = - x and x = - 3
<em>( - 3, 4 ) are coordinates of the centroid of the Δ ABC </em>
the answer is 97000
x=22°, y=50°, z=108°
x=22°(alternate angles are equal)
y=50°(angle sum in triangle is 180°)
z=108°
