Answer:

7x + 33

Step-by-step explanation:

Distribute the multiplication in the last term: 5(x + 6) becomes 5x + 30. Then, 2x + 3 + 5(x+ 6) becomes 2x + 3 + 5x + 30. 2x and 5x are 'like terms' and add up to 7x; 3 and 30 are also like terms of a different type (constants) and add up to 33.

Thus we have the equivalent, simpler expression 7x + 33.

Angle BOC = 120

PROOF

Angle A + Angle B + Angle C = 180

So, Angle B + Angle C = 120 (Angle A = 60)

Now 1/2 (Angle B + Angle C) = 60

1/2 Angle B + 1/2 Angle C = 60..............i

In triangle BOC

1/2 Angle B + 1/2 Angle C + Angle BOC =180

(BO and CO are angle bisectors)

Or 60 + Angle BOC = 180 (using i)

OR ANGLE BOC = 120
