How to find if a triangle is acute, right, or obtuse with the sides?
2 answers:
- An Acute angle is greater than 0 degrees lesser than 90 degrees.
- An Right angle is equal to 90 degrees.
- An Obtuse angle is greater than 90 degrees but lesser than 180 degrees
- An Right angle is equal to 90 degrees.
- An Obtuse angle is greater than 90 degrees but lesser than 180 degrees
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is actually pretty simple...
[attachment below will help too]
An obtuse triangle is where one angles is greater than 90*
A right triangle is where one angle is exactly equal to 90*
An acute triangle is where one angle is less than 90*
The BEST WAY to tell the difference between these triangles is to see/find either a 1/4 square (found on right triangles) or 1/3 circles (found on acute and obtuse triangles)...

- A function that models the data is given by this quadratic equation, y = -0.4908x² + 5.8845x + 1.3572.
- The number of students that are absent 10 days after the outbreak is equal to 11 students.
A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.
<h3>What is a quadratic function?</h3>A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the quadratic function is given by:
y = -0.4908x² + 5.8845x + 1.3572
For the number of students that are absent 10 days after the outbreak, we have:
y = -0.4908(10)² + 5.8845(10) + 1.3572
y = -0.4908(100) + 58.845 + 1.3572
y = -49.08 + 58.845 + 1.3572
Number of students, y = 11.12 ≈ 11 students.
