Triangle plane surface 2m base and 3 height

Click For Summary

Homework Help Overview

The discussion revolves around a triangle with a base of 2 meters and a height of 3 meters. Participants are exploring the properties of the triangle, particularly in relation to its centroid and the sine function in trigonometric contexts.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the derivation of certain values in the context of the triangle's dimensions, particularly the height and its relation to the sine function. There is also a focus on understanding the centroid's position within the triangle.

Discussion Status

The discussion is ongoing with various interpretations being explored. Some participants are seeking clarification on specific calculations and relationships, while others are providing insights into the geometric properties of the triangle.

Contextual Notes

There are indications of confusion regarding the application of trigonometric ratios and the definition of the triangle's height in relation to its base. Participants are also referencing external images for context, which may not be fully accessible to all.

Where are you ??
that question which I want only about sin

sin = o/h

but my Q now
h= 1 why
is because 3/3
or 2 / 2
or what please help me
 
Your question is unclear to me.
 
I mean
sin30 = y/1
So Xbar = 1.5 + y
So Xbar = 1.5 + 1Xsin30

Now my question from where we got (one)
Is by divide 3/3 as (h/3 ) = 1 or what ?.

please I want your help ?
 
The base of the triangle is the part closest to the surface. If triangle height is 3, the centroid of a triangle is 1/3 the distance from the base to the apex opposite the base. 1/3 of 3 is 1 and 1 is the hypotenuse.
 
thanks sooooooooooo much .. where are you before ... ^)^ ?
