Question

plzzzz plzzzz plzzzz solve it

Answer 1

Answer:

As the given C is midpoint of a A and B so it will divide the line segment joining A and B in the ratio 1 :1 internally .

So

$\frac{2a - 2}{2} = 1 \\ \implies2a - 2 = 2 \\ \implies2a = 4 \: \\ \implies \: a = 2$

Also

$\frac{4 + 3b}{2} = 2a + 1 \: \\ \implies4 + 3b = 10 \\ \implies \: 3b = 6 \\ \implies \: b =2$

show values of a and b will be 2 and 2 respectively.
