with it's formula
Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.
Answer:
(a+b,c)
Step-by-step explanation:
Note that the midpoint formula is:

Point A (0,0) and Point C (2a+2b,2c)
It follows that:

Answer:
-2r = 2 - Subtract 11 from both sides
r = -1
