1 degree is \dfrac\pi{180} radians. So 14 degrees is \dfrac{14\pi}{180}=\dfrac{7\pi}{90} rad.

Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also 2\pi radians. So the conversion rate is

\dfrac{2\pi\,\rm rad}{360^\circ}=\dfrac{\pi\,\rm rad}{180^\circ}

i.e. for every \pi radians there are 180º.

Answer:

\large\boxed{14^o=\dfrac{7\pi}{90}\ radians}

Step-by-step explanation:

\text{The formula for conversion of degrees to radians:}\\\\1^o=\dfrac{\pi}{180^o}\ radians\\\\x^o=\dfrac{x\pi}{180}\ radians\\\\\text{We have}\ x=14^o.\ \text{Substitute:}\\\\14^o=\dfrac{14\pi}{180}=\dfrac{7\pi}{90}

Can somebody help me on this?
irga5000 [103]

Answer:

x=28

Step-by-step explanation:

From the diagram we know that the angle m<3 = m<4 and the angle m<1 = m<2. Also we know that the sum of the four angles must be equal to 360.

Summarizing:

1. m<3 = m<4

2. m<1 = m<2

3. m<1 + m<2 + m<3 + m<4 = 360

Substituting 1 and 2 in equation three we have:

4. 2m<2 + 2m<3 = 360.

Now, we know that m<3 = 3x + 16 and m<2 = x + 84. Substituting in equation 4:

2 ( x + 84) + 2 ( 3x + 16) = 360

Solving for x:

2x + 168 + 6x + 32 = 360

8x = 224

x=28

Equation for perpendicular to the line -7x + 3y = -10j contains the point (-2,-4)
iogann1982 [59]

Answer:

y = 7/3x + 2/3

Step-by-step explanation:

-7x + 3y = -10

3y = 7x - 10

y = 7/3x - 10/3

-4 = 7/3(-2) + b

-4 = -14/3 + b

2/3 = b

How do you solve 5x-2x+6x+40-9+1-x+3x-8+15+7
Aleonysh [2.5K]

5x-2x+6x+40-9+1-x+3x-8+15+7

First you would combine like terms:

5x - 2x + 6x - x + 3x = 11x and

40 - 9 + 1 - 8 + 15 + 7 = 46, so the simplified expression would be

11x + 46
