Step-by-step explanation:
i have a different saying this so dont get mad
Solve like a linear algebra equation
use for slope
the b is intersept
We have the base measurement for the triangles composing the sides. We need their altitude.
Imagine a right triangle with these sides:
(1) from the apex of the pyramid to the point on the base directly underneath it (471 ft);
(2) from the middle of base edge to the point underneath the apex (half of 708 ft = 354 ft);
(3) the hypotenuse, the altitude of a triangular side.
Using the Pythagorean Theorem, we find the hypotenuse to be
√(471^2 + 354^2) = about 589.2 feet
Now we add up the four triangles' areas. Each is base * altitude / 2, so:
4 x 708 x 589.2 / 2
= 2 x 708 x 589.2
= 834,307.2 square feet, the lateral area.

Answer:
<h3>
45° or 55° {you didn't say which one is A}</h3>
Step-by-step explanation:
10x - 5° + 10x + 5° + 80° = 180°
20x = 100°
x = 5°
10x - 5° = 10×5° - 5° = 45°
10x + 5° = 10×5° + 5° = 55°
