# Vectors – Calculate median length and height length in a triangle – Exercise 4476

Exercise

Given

$$\vec{AB}=5\vec{i}+2\vec{j}$$

$$\vec{BC}=2\vec{i}-4\vec{j}$$

Calculate the length of the median AM and the length of the height AD of the triangle ABC.

$$|\vec{AM}|=6$$
$$|\vec{AD}|=\sqrt{28.8}$$
