you can use the value of sin\

sin(theta) = 12/16

Now solve for theta, and do inverse sine

so theta would be 48.59037789 , or around 50 degrees

Answer:

<h2>48.59°</h2>

Step-by-step explanation:

Since, it is a right triangle.

Perpendicular (p) = 12

hypotenuse ( h) = 16

now,

sin \: (x \: degree) =  \frac{perpendicular}{hypotenuse}

sin \: x \:  =  \frac{12}{16}

x =  {sin}^{ - 1} ( \frac{12}{16} )

x = 48.59 \: degree

hope this helps...

good luck on your assignment..

Answer:

Answer:

safe speed for the larger radius track u= √2 v

Explanation:

The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.

Also given that r_1= smaller radius

r_2= larger radius curve

r_2= 2r_1..............i

let u be the speed of larger radius curve

now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

................ii

form i and ii we can write

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v

Solve the system of equations.
slava [35]

Answer:

B

Step-by-step explanation:

Given the 2 equations

3x - 2y = 6 → (1)

5x + 4y = 32 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

6x - 4y = 12 → (3)

Add (2) and (3) term by term to eliminate y

11x = 44 ( divide both sides by 11 )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (2)

5(4) + 4y = 32

20 + 4y = 32 ( subtract 20 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

Solution is (4, 3 ) → B

X°+(x+30)=180°<br>I need answer​
djyliett [7]

Answer:

210 + -1x

Step-by-step explanation:

Simplifying

X + (x + -30) = 180

Reorder the terms:

X + (-30 + x) = 180

Remove parenthesis around (-30 + x)

X + -30 + x = 180

Reorder the terms:

-30 + X + x = 180

Solving

-30 + X + x = 180

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '30' to each side of the equation.

-30 + X + 30 + x = 180 + 30

Reorder the terms:

-30 + 30 + X + x = 180 + 30

Combine like terms: -30 + 30 = 0

0 + X + x = 180 + 30

X + x = 180 + 30

Combine like terms: 180 + 30 = 210

X + x = 210

Add '-1x' to each side of the equation.

X + x + -1x = 210 + -1x

Combine like terms: x + -1x = 0

X + 0 = 210 + -1x

X = 210 + -1x

Simplifying

X = 210 + -1x
