Step-by-step explanation:
The altitude of a triangle is a line segment through a vertex and perpendicular to a line containing the side opposite the vertex.
Answer: 
To answer this question we will use the following formula for compounded monthly interest:

where A₀ is the initial amount, r is the annual interest as a decimal number and 12 is the number of years.
Notice that:

Therefore, substituting t=42, r=0.02, and A₀=120000 we get:

Simplifying the above result we get:

Answer: $277,769.75.
