Determine if the triangles, △YPQ and △NPD, are similar. if so, Identify criterion.
Answers
Answer:
Yes, they are similar.
Criterion: AA Similarity
Explanation:
Looking at triangles YPQ and NPD, we can see that angles NPD and YPQ are vertically opposite angles and are congruent since vertically opposite angles are always congruent;
[tex]\angle YPQ\cong\angle NPD\text{ (vertically opposite angles)}[/tex]We can also observe that angles N and Y are congruent since they are alternate angles;
[tex]\angle N\cong\angle Y\text{ (alternate angles)}[/tex]From the AA similarity rule, we know that two triangles are said to be similar if two angles in one triangle are equal to two triangles in the other triangle.
Therefore, from the AA rule, we can say that triangles YPQ and NPD are similar.

And, the length of shadow of the shorter post is 0.85meter.
That implies,
Then,
[tex]\begin{gathered} \frac{2}{0.45}=\frac{x}{0.85} \\ x=\frac{2\times0.85}{0.45} \\ x=\frac{1.7}{0.45} \\ x=3.78m \end{gathered}[/tex]Hence, the length of the shadow of the longer post is 3.78m.
Choose either Yes or No to tell whether there is an angle of the given measure shown in the diagram.
Answers
The addition of all angles in the diagram is equal to 360 degrees. Let's call angle x to the unknown angle. Then, we have:
[tex]\begin{gathered} m\angle x+160\degree+40\degree+65\degree+25\degree=360\degree \\ m\angle x=360\degree-160\degree-40\degree-65\degree-25\degree \\ m\angle x=70\degree \end{gathered}[/tex]Therefore, there is an angle that measures 70°.
Combining the angles of 160°, 40°, and 65°, we get a new angle, let's call it y, that measures:
[tex]\begin{gathered} m\angle y=160\degree+40\degree+65\degree \\ m\angle y=265\degree \end{gathered}[/tex]Therefore, there is an angle that measures 265°.
Combining the angles of 160°, 70°, 25°, and 65°, we get a new angle, let's call it z, that measures:
[tex]\begin{gathered} m\angle z=160\degree+70\degree+25\degree+65\degree \\ m\angle z=320\degree \end{gathered}[/tex]Therefore, there is an angle that measures 320°.
Combining the angles of 25°, and 65°, we get a new angle, let's call it a, that measures:
[tex]\begin{gathered} m\angle a=25\degree+65\degree \\ m\angle a=90\degree \end{gathered}[/tex]Therefore, there is an angle that measures 90°.
On the other hand, there is no combination of angles that add up to 225°

The direction of the resultant vector is approximately 320°.
We have three vectors. The magnitudes of the vectors t, u, and v are 7, 10, and 15, respectively. The angles of the vectors t, u, and v are 240°, 30°, and 310°, respectively. We have to find the angle of the resultant vector of the sum of all three vectors. To add all the three vectors, we need to split the vectors into their horizontal and vertical components. The horizontal components are 7cos(240°), 10cos(30°), and 15cos(310°). The vertical components are 7sin(240°), 10sin(30°), and 15sin(310°).
Let the horizontal and vertical components of the resultant vector be denoted by H and V, respectively. The horizontal component is H = 7cos(240°) + 10cos(30°) + 15cos(310°) = 7*(-0.5) + 10*(0.866) + 15*(0.643) = -3.5 + 8.66 + 9.645 = 14.805. The vertical component is V = 7sin(240°) + 10sin(30°) + 15sin(310°) = 7*(-0.866) + 10*(0.5) + 15*(-0.766) = -6.062 + 5 - 11.49 = -12.552. The angle of the resultant vector can be calculated by the ratio of the components as tan(θ) = V/H = -12.552/14.805 = -0.848. So, the angle "θ" is approximately equal to 320°.

time can only take values greater than or equal to zero, so the domain starts on 0

Answers
Hello there. To solve this question, we'll have to remember some properties about percents.
We start with percent of increase: it is the difference between how much a thing is from another and 100%.
Now, to calculate this amount, we take the ratio of the numbers. In this case, the cost of a pound of nails.
Knowing it increased from $2.03 to $2.19, we calculate:
2.19/2.03 = 1.079
Multiply by 100% to find its amount in percent
1.079 * 100% = 107.9%
Now, we simply take the difference:
107.9% - 100% = 7.9%
Rounding this percent to the nearest whole-number percent, we get:
8%
