Answer:
16
Step-by-step explanation:
The formula for finding the length of a side of a right triangle is:
A^2 + B^2 = C^2 (c being the hypotenuse.)
We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.
20^2 - 12^2 = 256
or in simpler terms
20^2 - 144 = 256
Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation
16^2 + 12^2 = 20^2
or in simpler terms
256 + 144 = 400
So the length of the missing leg is 16. I hope this helps :)
Answer:
C. 16
Step-by-step explanation:
In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]
We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.
To find A, put the values you already have into the formula as follows:
[tex]A^2+12^2=20^2[/tex]
Next, square each value:
[tex]A^2+144=400[/tex]
Subtract 144 from 400 to simplify the equation.
[tex]A^2=256[/tex]
And finally, find the square root of 256 to find A.
[tex]A=16[/tex]
Final answer:
C. 16

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.
Answers
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

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

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?
Answers
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.

2/3p= 60? Step-by-Step explanation would be appreciated!
Answers
Answer:
p=90
Step-by-step explanation:
Divide 2/3 on both sides. When you divide a fraction, you actually
multiply by its reciprocal, or opposite (3/2).
2/3p=60
*3/2 *3/2
p=180/2
p=90
Hope this helps and have a great day C:
Answer:
p = 1/90
Step-by-step explanation:
determine the defined range
2/3p = 60, p = 0
then multiply both sides of the equation by 3p
2 = 180p
swap both sides of the equation
180p = 2
then Divide both sides of the equation by 180
p = 1/90 p = 0
check the solution is it in the defined range
then you should get your answers
