Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Given cot A = 63/16 and that angle A is in Quadrant , find the exact value of sin A in simplest radical form using a rational denominator.
Answer:
sin(A) = 16*Cos(A)/63
Step-by-step explanation:
You didn't state what quadrant it was in.
The sine of angle A is 16 / 65
What is the sine of an angle?In a right-angled triangle, the sine of an angle is equal to the ratio of the side opposite to the angle (also called perpendicular) and hypotenuse.
Give that, cot A = 63/16 and that angle A is in Quadrant, (refer to the figure attached)
Since, we know that, cotangent of an angle is ratio of adjacent side to opposite side.
Using Pythagoras theorem, we get,
63²+16² = 4255
√4225 = 65
Therefore, the hypotenuse = 65
sine of an angle = opposite side / hypotenuse
sinA = 16 / 65
Hence, the sine of angle A is 16 / 65

Q1. Prasha has five blocks of wood. The total weight of all five blocks of wood is 3 kilograms. 4 of the blocks of wood each have a weight of 650 grams. Work out the weight, in grams, of the other block of wood.
Answer: Weight of the remaining block of wood =400g
Step-by-step explanation:
Total Weight of five(5) blocks = 3kg = 3000g
Weight of 4 out of the 5 blocks = 650x 4= 2600g
Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks
= 3000g-2600g
=400g

Answer:
[tex](x-2)^2+(y-5)^2=9^2[/tex]
Step-by-step explanation:
We use the equation
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Now we plug in the numbers
(h, k) = center point (2, 5)
This would equal
[tex](x-2)^2+(y-5)^2=9^2[/tex]

A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submarine is 15.5 degrees. How deep is the submarine?
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]
sin(15.5°) = [tex]\frac{BC}{2500}[/tex]
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.

Find value of x pleaseee
Answer:
Step-by-step explanation:
you can use the side angle side formula ( a form of Law of Cosines)
a^2 = b^2 + c^2 − 2bc cos(A)
where x = a , then
[tex]x^{2}[/tex] = [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)
[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)
[tex]x^{2}[/tex] = 25 + 9 -8.7711511
x = 5.0228 cm
