Step-by-step explanation:
Find the coordinates of c using the section formula
= = = 3
= = = 2
coordinates of c = (3, 2)
Similarly to find the coordinates of d
= = =
coordinates of d = ( , )
h ≈ 11.9
Since the triangle is right we can use the cosine ratio to find h
cos24° = =
Multiply both sides by 13
13 × cos24° = h
⇒ h = 11.9 cm ( to 1 dec. place )
