What is the measure of the central angle AOB?
What is the measure of angle POB?
\angle AOB=360/5=72
\angle POB=\frac{\angle AOB}{2}
\angle POB=36
100
Find the area of the triangle on the grid.
A=(box)-(outside triangles)
A_(outside)=(5)(7)=35
A_(triangles)=(1/2)(3)(4)+(1/2)(1)(7)+(1/2)(5)(4)
A_(triangles)=6+3.5+10
A_(mixed)=35-19.5=15.5
