In an isosceles triangle KLM, ∠K is congruent to ∠M and m ∠M=55°. find the m ∠L

70°

Step-by-step explanation:

m ∠L = 180-(55+55)

= 180-110

=70°

275 ft

Step-by-step explanation:

The formula given to use for the slant height l of the cone is ;

l = (s - πr^2)/π

Now substituting the parameters given in the question, 500 π for area and radius of 15, we have

l = {500π-15^(2)π}/π

l =( 500 π -225 π)/π

l = 275 π/π

l = 275 ft
