Step-by-step explanation:
Two artillery bases are located at the points A and C represented in the figure. Each of the bases locates an enemy airplane at point B. The base at A measures the angles of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters. If the distance from the base at C to the plane is 2,517 meters, what is the measure, in degrees, of ∠CBA?
Answer:
the answer is 17 here is the step below
Step-by-step explanation:
Use the Law of Sines to find the distance. For a triangle with angles A, B, and C, and opposite sides a, b, and c, the Law of Sines states that sinAa=sinBb=sinCc.
In this case, the angle at point B, let it be α, needs to be found. The Law of Sines can be used to relate α, the two known sides, and the angle at point A.
The Law of Sines states that sinα739=sin95∘2517.
By simplifying, sinα=739sin95∘2517. Since α is acute, α=sin−1(739sin95∘2517)≈17.0∘.
The measure of the angle is 17 degrees if the A measures the angle of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture
To find the measure of the angle ∠CBA
Applying sin law:
sin95/2517 = sin∠CBA/739
0.292 = sin∠CBA
∠CBA = sin⁻¹(0.292)
∠CBA = 17 degrees
Thus, the measure of the angle is 17 degrees if the A measures the angles of elevation to the airplane to be 95∘ and the distance between the two bases is 739 meters.

d=.5*a*t^2 - solving for a[tex]d=.5*a*t^2[/tex]
Answer:
[tex]\displaystyle a=\frac{d}{.5*t^2}[/tex]
Step-by-step explanation:
Equation Solving
We are given the equation:
[tex]d=.5*a*t^2[/tex]
It's required to solve it for a.
Swap sides to have the letter on the left side:
[tex].5*a*t^2=d[/tex]
Divide by [tex].5*t^2[/tex]:
[tex]\mathbf{\displaystyle a=\frac{d}{.5*t^2}}[/tex]

porque yo so muy inteligente,la reina...Point-slope form
Complete the point-slope equation of the line through (8, —8) and (9.8).
Use exact numbers.
y-8=
Answer:
The equation in point-slope form is:
[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
The equation of the line in slope-intercept form is:
[tex]y=16x-136[/tex]
Step-by-step explanation:
Given the points
(8, -8)
(9, 8)
Finding the slope between (8, -8) and (9, 8)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(8,\:-8\right),\:\left(x_2,\:y_2\right)=\left(9,\:8\right)[/tex]
[tex]m=\frac{8-\left(-8\right)}{9-8}[/tex]
[tex]m=16[/tex]
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here:
m is the slope and (x₁, y₁) is the point
substituting the values m = 16 and the point (8, -8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
Thus, the equation in point-slope form is:[tex]y-\left(-8\right)=16\left(x-8\right)[/tex]
now completing the point-slope form equation of the line
[tex]y+8=16\left(x-8\right)[/tex]
subtract 8 from both sides
[tex]y+8-8=16\left(x-8\right)-8[/tex]
[tex]y=16x-136[/tex]
Thus, the equation of the line in slope-intercept form is:[tex]y=16x-136[/tex]

Answer:
36=b^2 or b=the square root of 36
Step-by-step explanation:
The sides of a square are all equal in length. To find the area of a square you can multiply the two sides together. Considering that they are the same length, you can just square one of the side lengths to get your answer. To find a side length you can take the square root of the area.
