Solution

The formula for the area of a sector is given by:

Area = (θ/360) * π * r²

where: θ is the angle of the sector, r is the radius of the circle.

Given that the area is 52 in² and the radius is 10 in, we can substitute these values into the formula and solve for θ:

52 = (θ/360) * π * 10²

Solving this equation for θ gives:

θ = (52 * 360) / (π * 10²)

Calculating this gives:

θ ≈ 59.24 degrees

So, the measure of the angle of the sector is approximately 59.24 degrees.
