Julianne wants to find the surface area of a pyramid. the base is a square with sides that are 4 inches long. the other faces are isosceles triangles. the ratio of the height of each triangle to its base is 3: 2
part a: give the base length and the height of each triangular face
part b: find the combined area of the triangular faces
part c: find the surface area of the pyramid
pls answer !

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

what are the statments
