1. Answer;
- Triangle
Explanation;
The cross section formed by a plane that contains a vertical line of symmetry for a tetrahedron is a Triangle.
A tetrahedron also a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners.
2. Answers
- Triangle
Explanation;
The cross section formed by a plane that intersects three faces of a cube is a Triangle. A cross section is the shape we get when cutting straight through an object. The shape of the cross-section of a solid depends upon the orientation of the cutting plane to the solid.
Answer:
formula is 6a²= surface area
but since one side is not being painted it is
5a²= surface area
5(3.2)²
=51.2cm
What's 111111 - 3 + 34. Whoever gets it right, we will do brainliest for brainliest.
that would 111142
Answer:
2. 2.3
3. 37.2 m
Step-by-step explanation:
2. tan theta = opposite/ adjacent
tan 25 = x/5
Multiply each side by 5
5 tan 25 = x/5 *5
5 tan 25 = x
2.331538291
To the nearest tenth
2.3 =x
3. We want to find the height or y
sin theta = opposite/ hypotenuse
sin 60 = y /43
Multiply each side by 43
43 sin 60 = y/43 * 43
43 sin 60 = y
37.23909236 = y
To the nearest tenth
37.2 =y
The light pole is 37.2 meters tall
