20 POINTS!In this unit, you worked with geometric proofs. A proof is a logical sequence of justified conclusions that lead from

a hypothesis to a final conclusion. In your opinion, why are mathematical proofs important? Suppose that a conclusion within a proof isn’t justified or is inaccurate. In geometry, what might be the consequences of the inaccuracy? Now think about different kinds of proofs that take place outside the world of geometry, and list a few examples. What might be the consequences of having an unjustified conclusion surface in such proofs? Who might be affected and how?

Not only in mathematics, scientific proof also are required in the other field of science. Also maths proofs are of particular structure, containing steps and logics. So proving is like doing science, it is science. That's why it is important to prove. 
An inaccurate proof leads to errors, or stating results that are not accurate. 
Example 1:
If the derivative of a function is negative, then the function is decreasing. 
Example 2:
The sum of the measures of the angles of any triangle is 180°.
Example 2:
Given a triangle whose vertices are on a circle and one side is the 
diameter of the triangle, then the triangle is right angled.

Answer: Not only in mathematics, scientific proof also are required in the other field of science. Also maths proofs are of particular structure, containing steps and logics. So proving is like doing science, it is science. That's why it is important to prove.

An inaccurate proof leads to errors, or stating results that are not accurate.

Example 1:

If the derivative of a function is negative, then the function is decreasing.

Example 2:

The sum of the measures of the angles of any triangle is 180°.

Example 2:

Given a triangle whose vertices are on a circle and one side is the

diameter of the triangle, then the triangle is right angled.

Type the correct answer in the box Round your answer to the nearest integer. You are standing at a certain distance from a build
miskamm [114]

Answer:

<em />

55 degrees

<em />

Step-by-step explanation:

<em />

In the initial position, the angle of elevation of the 20 meter building to your feet is 45 degrees, that means that you are at 20 meters from the building (thus forming an isosceles triangle with with the building, with internal angles 456  degrees, 90 degrees, and 45 degrees.

<em />

When you walk 6 meters towards the building, you are now at 14 meters from it. Therefore you need to examine now another triangle where the angle is unknown but for which you know the opposite side (20 meters of the building's height), and the adjacent side (14 meters of your distance to the building). See image attached for more clarity on the picture you need to study.

<em />

The tangent of this new angle is defined as opposite side divided by adjacent (opp/adj) which in our case renders 20/14 = 10/7

<em />

So to find the angle, we need to apply the arctangent function to this value.

<em />

Therefore:

<em />

<em>new angle = arctan(10/7) = 55 degrees</em>

<em />

IN THE LAST TWO WEEKS , A PLANT GREW 1/16 IN. AND 3/16 IN. RESPECTIVELY
grandymaker [24]
I'm assuming you mean that the plant grew 1/16th of an inch the first week, and 3/16th of an inch the next week. Simply add the two together (4/16th) and simplify. Since four goes into both numbers, the simplified version is 1/4th. Hope this helps
