Answer:less than
Step-by-step explanation:
1/5 x 2 1/5 = 11/25
2 1/5 as a mixed number is 11/5
so 11/25 is less than 11/5 therefore
1/5 x 2 1/5 < 2 1/5
Answer:
m∠A ≈ 103°
Step-by-step explanation:
Enough information is shown for us to be able to use the Law of Sines to find the angle. That tells us ...
sin(A)/a = sin(C)/c
A = arcsin(a/c·sin(C)) = arcsin(26/6·sin(13°)) = arcsin(0.974788)
A = 77.1° or 102.9°
The claim is that the figure is drawn to scale, so we can assume that A is an obtuse angle:
m∠A ≈ 103°

<em>Additional comment</em>
The sum of angles A and B must be 180° -13° = 167°. Since angle A is the largest, it must be more than half this value, or more than 83.5°. That means, we must choose the obtuse angle for A, rather than the acute angle.

Answer:
All the lateral faces in a triangular pyramid are congruent.
Step-by-step explanation:
- A triangular pyramid is a pyramid that has a triangular-shaped base.
- It has equilateral triangles which are equilateral.
- The pyramid is also known as tetrahedron because the base is of triangular shape.
- There are four faces and a triangular base in a triangular pyramid.
- There are four vertices and six edges.
