Item 7
△ABC has vertices A(−1, 2), B(2, 8), and C(4, 1). Find the measure of each angle of the triangle. Round decimal answers to the nearest tenth.
Answer:
[tex]A = 74.7^\circ[/tex]
[tex]B = 42.5^\circ[/tex]
[tex]C = 62.8^\circ[/tex]
Step-by-step explanation:
Given
[tex]A = (-1,2) \to (x_1,y_1)[/tex]
[tex]B = (2,8) \to (x_2,y_2)[/tex]
[tex]C = (4,1) \to (x_3,y_3)[/tex]
Required
The measure of each angle
First, we calculate the length of the three sides of the triangle.
This is calculated using distance formula
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
For AB
[tex]A = (-1,2) \to (x_1,y_1)[/tex]
[tex]B = (2,8) \to (x_2,y_2)[/tex]
[tex]d = \sqrt{(-1 - 2)^2 + (2 - 8)^2[/tex]
[tex]d = \sqrt{(-3)^2 + (-6)^2[/tex]
[tex]d = \sqrt{45[/tex]
So:
[tex]AB = \sqrt{45[/tex]
For BC
[tex]B = (2,8) \to (x_2,y_2)[/tex]
[tex]C = (4,1) \to (x_3,y_3)[/tex]
[tex]BC = \sqrt{(2 - 4)^2 + (8 - 1)^2[/tex]
[tex]BC = \sqrt{(-2)^2 + (7)^2[/tex]
[tex]BC = \sqrt{53[/tex]
For AC
[tex]A = (-1,2) \to (x_1,y_1)[/tex]
[tex]C = (4,1) \to (x_3,y_3)[/tex]
[tex]AC = \sqrt{(-1 - 4)^2 + (2 - 1)^2[/tex]
[tex]AC = \sqrt{(-5)^2 + (1)^2[/tex]
[tex]AC = \sqrt{26[/tex]
So, we have:
[tex]AB = \sqrt{45[/tex]
[tex]BC = \sqrt{53[/tex]
[tex]AC = \sqrt{26[/tex]
By representation
[tex]AB \to c[/tex]
[tex]BC \to a[/tex]
[tex]AC \to b[/tex]
So, we have:
[tex]a = \sqrt{53[/tex]
[tex]b = \sqrt{26[/tex]
[tex]c = \sqrt{45[/tex]
By cosine laws, the angles are calculated using:
[tex]a^2 = b^2 + c^2 -2bc \cos A[/tex]
[tex]b^2 = a^2 + c^2 -2ac \cos B[/tex]
[tex]c^2 = a^2 + b^2 -2ab\ cos C[/tex]
[tex]a^2 = b^2 + c^2 -2bc \cos A[/tex]
[tex](\sqrt{53})^2 = (\sqrt{26})^2 +(\sqrt{45})^2 - 2 * (\sqrt{26}) +(\sqrt{45}) * \cos A[/tex]
[tex]53 = 26 +45 - 2 * 34.21 * \cos A[/tex]
[tex]53 = 26 +45 - 68.42 * \cos A[/tex]
Collect like terms
[tex]53 - 26 -45 = - 68.42 * \cos A[/tex]
[tex]-18 = - 68.42 * \cos A[/tex]
Solve for [tex]\cos A[/tex]
[tex]\cos A =\frac{-18}{-68.42}[/tex]
[tex]\cos A =0.2631[/tex]
Take arc cos of both sides
[tex]A =\cos^{-1}(0.2631)[/tex]
[tex]A = 74.7^\circ[/tex]
[tex]b^2 = a^2 + c^2 -2ac \cos B[/tex]
[tex](\sqrt{26})^2 = (\sqrt{53})^2 +(\sqrt{45})^2 - 2 * (\sqrt{53}) +(\sqrt{45}) * \cos B[/tex]
[tex]26 = 53 +45 -97.67 * \cos B[/tex]
Collect like terms
[tex]26 - 53 -45= -97.67 * \cos B[/tex]
[tex]-72= -97.67 * \cos B[/tex]
Solve for [tex]\cos B[/tex]
[tex]\cos B = \frac{-72}{-97.67}[/tex]
[tex]\cos B = 0.7372[/tex]
Take arc cos of both sides
[tex]B = \cos^{-1}(0.7372)[/tex]
[tex]B = 42.5^\circ[/tex]
For the third angle, we use:
[tex]A + B + C = 180[/tex] --- angles in a triangle
Make C the subject
[tex]C = 180 - A -B[/tex]
[tex]C = 180 - 74.7 -42.5[/tex]
[tex]C = 62.8^\circ[/tex]

Answer:
x = 29.69
Step-by-step explanation:
Since the Adjacent side of the given angle 38, is given, and opposite needs to be found out, we will us the Tangent ratio:
Tan(38) = [tex]\frac{x}{38}[/tex]
=> To isolate x all by itself, multiply 38 from the right side of "=", on both sides;
Tan(38) * 38 = x
29.69 = x

Chase is a contestant on a game show. His scores in each of the first four
rounds are shown below. Chase's final score is double his score after the
four rounds. What is Chase's final score? Show your work
Answer:
the final score of chase is 170
Step-by-step explanation:
Given that
The chase final score would be double his score after the four rounds
So the chase final score is
= (Round 1 score + round 2 score + round 3 score + round 4 score) × 2
= (-35 + 45 + 90 - 15) × 2
= 170
Hence the final score of chase is 170
The same would be considered and relevant

what is the surface area of the cylinder with height 8 ft and radius 3 ft round your answer to the nearest thousand.
Answer:
207.24
Step-by-step explanation:
[tex]S_{surface} = S_{side} + 2*S_{base} \\S_{side} = 2\pi RH\\ = 2*3.14*3*8=150.72\\S_{base} = \pi R^{2} = 3.14 * 3^{2} = 28.26\\S_{surface} = 150.72 + 2* 28.26 = 207.24[/tex]

Answer:
The probability of getting a 1, 2, 3 on three rolls respectively is [tex]\frac{1}{216}[/tex].
Step-by-step explanation:
Since you are rolling three dies, and each die has six sides, that means there are a total of 216 possible outcomes. Out of the 216 different outcomes, only 1 of them meet the requirement of rolling a '1' on the first die, a '2' on the second die, and a '3' on the third die, so the fraction to represent the situation would be [tex]\frac{1}{216}[/tex].
If A and B are mutually exclusive events then the probability of A happening OR the probability of B happening is P(A) + P(B).

7. Solve for x:
8. Find m
Answer:
From Triangles...
The sum of two opposite interior angles = the exterior
so
3x-2 + 9x + 7 = 14x - 19
12x +5=14x -19
Collecting Like terms
2x= 24
x= 12°.
For "m"
Sum of angles in a triangle=180°
So
180 - (19x-3+9x-2) = m
180 -(28x -5) =m
m= 180 - 28x + 5
m=185 - 28x.
Now
Since sum of everything in a triangle = 180
185 - 28x + 9x -2 + 19x - 3 = 180
185 -28x + 28x -5= 180
185-5=180
180=180

El punto p se muestra en la recta numerica.
La distancia entre el punto Q y el punto P es de 6 1/2 unidades . Que numero podria representar el punto Q ?
Answer:
2 1/2 o 10 1/2
Step-by-step explanation:
q podría estar 6.5 unidades a la derecha ... oa la izquierda ... del punto p.
a la derecha: p + q ⇒ -4 + (6 1/2) = 2 1/2
a la izquierda: p - q ⇒ -4 -(6 1/2) = -10 1/2

Answer: 240.6cm *squared*
Step-by-step explanation:
Surface Area= (2 x Area of 1st face) + (2 x Area of 2nd face) + (2 x Area of 3rd face)
= (2 x 10.5cm x 5.4 cm) + (2 x 10.5 cm x 4.0cm) + (2 x 5.4cm x 4.0cm)
= 113.4cm*squared* + 84.0cm *squared* + 43.2cm *squared*
= 240.6cm *squared*
OR
= 2 x (sum of the 3 faces)
= 2 x (56.7cm * squared* + 42.0cm *squared* + 21.6cm *squared*)
= 2 x 120.3cm *squared*
= 240.6cm *squared*

The sophomore class is organizing a picnic and bought 1300 hot dogs and hamburgers for the event. The hotdogs cost $0.59 each and the hamburgers cost $0.98 each before tax. The total bill came to $1041.37, which
included $79.37 in tax. Write only the system you would use.
0.59 h + 0.98 b = 1041.37 - 79.37
h + b = 1300
