Find the area of the shaded region. (two triangles are shaded that make vertical angles inside a circle) the radius is 8 inches and the measure angle is 125.
+130511 I don't see any diagram, but just taking a guess, we want to find the area of two congruent isosceles triangles in a circle whose equal sides are 8 and the included angle between these sides is 125°. Also......I'm assuming that these vertical angles are central angles in the circle.....if so, the area =
(8^2) * sin(125) = about 52.426 in^2
