Find the area of the lighter shaded region
-it’s 80 degrees inside the triangle

9514 1404 393
Answer:
5.1 cm²
Step-by-step explanation:
The area of a sector is given by ...
A = 1/2r²(θ -sin(θ)) . . . . where θ is the central angle in radians.
For this geometry, the area is ...
A = (1/2)(5 cm)²(80π/180 -sin(80°)) ≈ 5.1 cm²
