Answer:
a=21°b=70°c=89°
Step-by-step explanation:
a=21°[by vertical opposite angle]
b+110°=180°[by linear angle]
b=180°-110°=70°
a+b+c=180°[by sum of all angle]
21°+70°+c=180
91°+c=180°
c=180°- 91°
c=89°
Answer:
A plane has an unlimited number of points.
Step-by-step explanation:
A plane has an unlimited number of points.
An exact solution represents a point's position on the coordinate plane (x, y).
Even though a point has no dimensionality, the second assertion is incorrect.
Because a linear has only one component, length, the third assertion is likewise incorrect.
