Hi I have another question that I need to get confirmed that I've done it correct. "In triangle ABC, BC = 6.8 cm, angle B = 54° and angle C = 43°. Find the shortest distance from point A (angel A) to side BC." This is how I solved it. The shortest distance from point A to side BC, is the height of the triangle, isn't it? The key says the answer is 3.8 cm. I was just wondering if I'm thinking correct, that the height from point A to side BC is the shortest distance.

Yes, the shortest distance from a point to a line is the perpendicular distance.

The height is indeed the shortest distance between the point A and the opposit side.
