Answer:
p ≈ 17.6
a = 10.5
Step-by-step explanation:
AC = 3
BC = 7
use pythagorean theorem to find AB
AB² = 3² + 7²
AB² = 58
AB = 7.615773105863908
AB ≈ 7.6
-------------------------------
Perimeter
p ≈ 3 + 7 + 7.6
p ≈ 17.6
Area
a = (1/2)bh
a = (1/2)3 * 7
a = 10.5
Answer:
1.What are elliptic geometries
2.what are hyperbolic geometries?
3.why was elliptic geometries developed
4.why was hyperbolic geometries developed?
Step-by-step explanation:
1.Elliptic geometry is a non-Euclidean geometry with positive curvature which replaces the parallel postulate with the statement "through any point in the plane, there exist no lines parallel to a given line.
2 .Hyperbolic geometry, also called Lobachevskian Geometry, a non-Euclidean geometry that rejects the validity of Euclid's fifth, the “parallel,” postulate. ... In hyperbolic geometry, through a point not on a given line there are at least two lines parallel to the given line.
3.Felix Klein (1849–1925) modified the model by identifying each pair of antipodal points as a single point, see the Modified Riemann Sphere. With this model, the axiom that any two points determine a unique line is satisfied. Often an elliptic geometry that satisfies this axiom is called a single elliptic geometry.
4.The complete system of hyperbolic geometry was published by Lobachevsky in 1829/1830, while Bolyai discovered it independently and published in 1832.

<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>
