Answer:

a)

b) SSA does not constitute a proof. You need another fact.

Step-by-step explanation:

You should actually show congruency first

Angles opposite = sides are themselves equal.

<C = 50o

<J = 50o

But there is nothing that says x is 1/2 of <JAC

So it's unsolvable

Part B also has the same conclusion.

Find the surface area of the square pyramid below if the length of the sides of the base are 10 cm, and the slant height is 15 c
Damm [24]

The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²

<h3>Surface area</h3>

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

where,

  • a = sides of base = 10 cm
  • h = slant height = 15 cm

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

= 10² + 2(10)√10²/4 + 15²

= 100 + 20√100/4 + 225

= 100 + 20√25 + 225

= 100 + 20√250

= 100 + 20(15.81)

= 100 + 316.2

= 416.2 cm²
