Answer:
4x°= 4x18= 72°=measure of angle SQR
Step-by-step explanation:
6x +4x = 180
10x = 180
x = 180/10
x= 18°
because m L SQR =4x°
now place the value of x in the above equation
m L SQR = 4 x(18°)= 72°

Answer:
b
Step-by-step explanation:
centroid
x=(x1+x2+x3)/3=(0+3+0)/3=3/3=1
y=(y1+y2+y3)/3=(0+0-3)/3=-3/3=-1
centroid =(1,-1)
