Surface Tension ||Surface tension Force and Surface Energy

Surface tension||Soap bubble and drop||Surface energy

Excess pressure inside a soap bubble of radius r and surface tension T is

The force of surface tension acts tangentially to surface whereas the force due to air pressure perpendicularly on the surface. How is then due to excess pressure inside a bubble bal force due to the surface tension ?
