Answer :

Rough Diagram:

Construction Steps:

__Step 1:__ Draw the ΔABC with the given measurements.

__Step 2:__ Construct altitudes from any two vertices (A and C) to their opposite sides (BC and AB) respectively.

The point of intersection of the altitudes H is the orthocenter of the given ΔABC.
