Angle sum property of triangle states that, sum of interior angles of a triangle is 180°. prove Start with the following triangle with arbitrary values for the angles: Angle sum theorem Since angle a, angle b, and angle c make a straight line, angle a + angle b + angle c = 180 degrees Since alternate interior angles are equal, angle a = angle x and angle b = angle y Therefore, angle x + angle y + angle c = 180 degrees ...

Radius (r) of the base of cone = 10.5/2

= 5.25 cm

Slant height (l) of cone = 10 cm

CSA of cone = πrl

= 22/7 × 5.25 × 10
= 22 × 0.75 × 10

= 165 cm²

Therefore, the curved surface area of the cone is 165 cm²
