Find m∠E.

m∠E= ___∘

HELP 20 points

55

Step-by-step explanation:

Angle C = Angle D (Corresponding Angles)

Therefore, BD//AC

Angle A = Angle B (Corresponding Angles)

=>6x-15=5x-1

=>6x-5x=-1+15

=>x=14

Angle B=5x-1

            =5(14)-1

            =70-1

            =69

Angle D=4x

            =4(14)

            =56

Angle E=180-(Angle D+ Angle B)          [Angle Sum Property]

            =180-(69+56)

            =180-125

            =55

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
