Answer:

1) Two concepts that are related but not the same are supplementary angles and complementary angles. The difference is their sum. Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.

2)Whenever two lines intersect, they form two pairs of vertical angles. Vertical angles have a common vertex, but they are never adjacent angles. Finally, vertical angles are always congruent.

3)The sum of the lengths of any two sides of a triangle is greater than the length of the third side. If you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. If that is not true, then it is not possible to construct a triangle with the given side lengths.

4) The area is 201.06

The circumference is 50.27

[don't really know how to explain so here are the formulas, (hope it helps)

C(circumference)= 2 x pi x r(radius)

A(area)= pi x r(radius)^2

5) Unique Triangles are Triangles that do not have an equivalent. This means there is not another triangle that has the exact dimensions or shape. The sets of facts or conditions that you need to know to create an unique triangle.

Answer:

complematry is like a small triangle and the supplementrey is the bigger triangle.

2- they have 4 sides and they can be used for anything

3- linear and the top of an triangle to the bottom of it.

4- 16 just times it by 2

5- triangle pyramid and the regular triangle

6-top to down, side to side, and and bottom to top sideways.

While surveying Overlook Cave, Mike measures the angle of elevation from his line of sight to the top of a rock formation as 22°

Kaylis [27]

Answer:

The rock formation is approximately 7 feet tall.

Step-by-step explanation:

We can visualize this situation as a triangle and know that the bottom side is 10 and the angle of elevation (the angle created by Mike and the ground, looking to the top of a rock). With this information, we can use tangent to solve.

x = the height of the rock formation

tan(22°) = x/10

10 tan(22°) = x

x = ~4.04 feet

We also have to add the 3 feet to it because it is being measured 3 feet above the floor.

x + 3 = 7.04 feet

Simplify the following surd expressions a) 7/3 - 2/3 + V3 - 3V3

Nata [24]

Answer:

$\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}$

Step-by-step explanation:

Given the expression

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:v^3\:-\:3v^3$

solving the expression

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}$

combine the fractions i.e $\frac{7}{3}-\frac{2}{3}=\frac{5}{3}$

$\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}=\frac{5}{3}+\sqrt{3}-3\sqrt{3}$

add similar elements i.e $\sqrt{3}-3\sqrt{3}=-2\sqrt{3}$

$=\frac{5}{3}-2\sqrt{3}$

Thus,

$\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}$

Y=|x−5|+|x+5|, if x>5

Sidana [21]

Hello,

Let me try out the solution for you.

Consider the below scenarios for the equation y = |x+5|-|x-5|

Case 1:

when x more than or equal to 5

then y=(x+5)-(x-5) = 10

hence y=10

Case 2:

when -5<x<5

y=(x+5)-(-(x-5)) = 2x

y=2x so y can take 9 values corresponding to x={-4,-3,-2,-1,0,1,2,3,4}

Case 3:

when x less than or equal to -5

y= -(x+5)-(-(x-5))

y=-10

Hence if we combine all 3 cases we get that y can take total of 11 values.

Pls help i’ll be giving a brainliest to the person with the correct answer

Answer:

the slope is positive

Step-by-step explanation:

Notice that as x is increasing, g(x) is also increasing. Therefore, the slope is positive. If you were to plot those points and draw the line thru them, you would see that the line goes up as x increases. A line that does that has a positive slope. Another way to look at it is to see that the change in g(x) is positive as the change in x is also positive.

The slope is change in g(x)/change in x.

So, you have positive/positive = positive.

There are several ways to solve this problem. I just gave you 3 of them.
