P(0,0) and R(2b, 2c)
Midpoint:
x = (x1+x2)/2 and y=(y1+y2)/2
Midpoint PR
x = (0 + 2b)/2
= 2b/2
=b
y = (0 + 2c)/2
=2c/2
=c
Midpoint PR (b,c)
Answer is the last one
(b,c)
The sum of the interior angles of any triangle is 180 degrees. It does not depend on which triangle we are discussing that this fact is true for all triangles. 180 degrees is a straight line.
Yes you are correct
60 * 360 / 40 = 540
The following are true:-
First choice
Third choice.
The last choice
(1,2) is a solution to the system of equations
