Bob placed three regular pentagons together at a vertex, thinking he might be able to form a tessellation. However, they left a gap. What is the number of degrees in the measure indicated?

the pentagon has equal angles so the inside angle is 108 to get  360 the circle angle inside 108+108=216 360-216=144
