Please help

Step-by-step explanation:

b/c we know that these triangles both have equal sides... that is given that ab and be are the same length.   and that be and cd are parallel , we know that they both are isosceles triangles and that the base angles are the same.  The side on ad and ae  have equal angles.

so we can make the equation

2a +56 = 180  (b/c we know that around a triangle it's 180°

2 a = 124

a = 62

so ∠ BAE = 62°

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
