Given information
It is given that there is a round arch and pointed arch
Also the horizontal force exerted by pointed arch is one-third the horizontal force exerted by round arch 
Step-by-step explanation
Step 1.
Round arch and its free body diagram is as shown below :
represents the weight of load equally divided into 2 forces acting on either side of the center of arch, horizontal force and upward force which supports the arch to be in equilibrium respectively
acts at point 
from the top center of arch
For rotational equilibrium, each support exerts a horizontal force, at the base of the arch
At both end of the arch same forces act and the arch is in equilibrium
