Answer:
Approximately [tex]36^{\circ}[/tex], assuming that the tree is upright.
Step-by-step explanation:
Refer to the diagram attached. The upright tree and its shadow are in a right triangle. In this right triangle, the angle of elevation of the sun would be the angle adjacent to the shadow of this tree. At the same time, this angle would be opposite to the side representing the tree. Thus, the tangent of this angle could be represented as:
[tex]\begin{aligned}\tan(\text{angle of elevation}) &= \frac{\text{opposite}}{\text{adjacent}} \\ &= \frac{10\; \text{yard}}{14\; \text{yard}} \\ &= \frac{5}{7}\end{aligned}[/tex].
Take the arctangent of this value to find the measure of this angle:
[tex]\begin{aligned} (\text{angle of elevation}) &= \arctan(\tan(\text{angle of elevation})) \\ &= \arctan\left(\frac{5}{7}\right) \\ &\approx 0.620 \times \frac{360^{\circ}}{2\, \pi} \\ &\approx 36^{\circ}\end{aligned}[/tex].
Thus, the angle of elevation of the sun at this moment would be approximately [tex]36^{\circ}[/tex].

90 in²
Step-by-step explanation:Area is the amount of space a 2-D shape occupies.
Area Formula
As stated above, the area of a triangle is [tex]\frac{1}{2}bh[/tex]. When solving for area, it doesn't actually matter which side is the base. You just have to remember to take the height perpendicular to the base you use. Since this is a right triangle, the height is the same as one of the legs. For the purpose of this question, I will use 12 as the base and 15 as the height. Because the 12 and 15 sides are perpendicular to each other, we can plug them into the formula for b and h.
Solving For A
Now we can just plug 12 and 15 in and solve.
[tex]\frac{1}{2}*12*15 = 90[/tex]The area of the triangle is 90 in².

Answer:
[tex]y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
Step-by-step explanation:
Given equation:
[tex]\pi=7x-2y[/tex]
To isolate y, add 2y to both sides:
[tex]\implies\pi+2y=7x-2y+2y[/tex]
[tex]\implies\pi+2y=7x[/tex]
Subtract π from both sides:
[tex]\implies\pi+2y - \pi=7x- \pi[/tex]
[tex]\implies 2y=7x- \pi[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{2y}{2}=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
[tex]\implies y=\dfrac{7x}{2}- \dfrac{\pi}{2}[/tex]
This can also be written as a rational function:
[tex]\implies y=\dfrac{7x- \pi}{2}[/tex]
Answer:
y = (-π + 7x)/2
Step-by-step explanation:
Now we have to,
→ find the required value of y.
The equation given is,
→ π = 7x - 2y
Then the required value of y will be,
→ π = 7x - 2y
→ -2y = π - 7x
→ y = (π - 7x)/(-2)
→ [ y = (-π + 7x)/2 ]
Hence, the equation is (-π + 7x)/2.

How do you know that 30 is 1/10 of 300.
Answer: Division
Step-by-step explanation: It's simple. 1/10 = divided by 10. So, all you have to do is divide 10 by 300 and get your answer
Hey there!
1/10 of 300 = 30
1/10 * 300 = 30
1/10 * 300/1 = 30
1(300)/10(1) = 30
300/10 = 30
300 ÷ 10 / 10 ÷ 10 = 30
30 / 1 = 30
30 ÷ 1 = 30
30 = 30
Therefore, your could say you: Simplified your given equation (1/10 * 300) like how I did above and you received the answer (30) & the statement is very much true
Good luck on your assignment & enjoy your day!

The conjecture about backpack sales is that June sales will be less than 8,000 units.
What is a conjecture?
A conjecture is a mathematical statement without proof. Instead, conjectures survive on some existing patterns.
The existing patterns show that backpack sales peaked in November but deteriorated or decreased steadily every month.
For instance, in November, the backpack sales were 11,000 units but 10,250 in January. It reduced to 8,750 in March.
However, following the end of the Easter holidays, backpack sales may increase from May. But this prediction does not agree with the trend.
Thus, the conjecture about backpack sales is that June sales will be less than 8,000 units.

A parking lot is 126.1 m long and 38.06 m wide, what is the perimeter of the lot? Express your answer using four significant figures.
Two triangles are drawn in the coordinate plane. The vertices of the first triangle are (5, 4), (-4, 6), (-8, 9). The vertices of the second triangle are (1, 6), (-8, 8), (x, y). Find the value of x and y that allow these two triangles to be congruent.
The value of x and y that allows these two triangles to be congruent is
(-12, 11)
What are congruent triangles?The congruence of two or more triangles is determined by the measurements of their sides and angles. The three sides of a triangle determine its size, and the three angles determine its shape.
Two triangles are said to be congruent if the pairs of their corresponding sides and angles are equal. They are the same size and shape. Triangles have numerous congruence conditions.
Here we will use translation to find out units of displacements
If the triangle is congruent then vertices are of same shape too which means coordinate of first triangle will give us coordinate of second triangle
The coordinates of 1st vertices of traingle1 = (5, 4), x = 5, y = 4
The coordinates of 1st vertices of traingle2 = (1, 6), x = 1, y = 6
By subtracting,
translation x = 5 - 1 = 4
translation y = 4 - 6 = -2
Thus the vertices of other triangles are translated 4 units left and 2 units up. Same goes for second vertices
-4 - 4 = 8
6 + 2 = 8
And the same will go for the last vertices (-8, 9) that is
-8 - 4 = -12
9 + 2 = 11
The value of x and y that allow these two triangles to be congruent is (-12, 11)

Is collecting pennies dependent or an independent events?
Collecting pennies can either be a dependent or an independent events based on the scenario.
How to illustrate the information?Events classified as independent do not depend on other events for their occurrence. For instance, if we toss a coin in the air and it lands on head, we can toss it again and this time it will land on tail.
A coin toss is an illustration of an autonomous occurrence. With each toss of the coin, there is an equal probability (0.5) of either heads or tails occurring, presuming that the coin is fair and can only land on heads or tails. It doesn't matter if the coin came up heads on the prior toss.
In conclusion, collecting pennies can either be a dependent or an independent events based on the scenario.

But bare in mind, if you used the first coordinate x as x1 you must used the y coordinate as the y1. you must use the same order. so if you used X2 for second coordinate use y2 for the y point of the second coordinate.
