Step-by-step explanation:

This is simple. I'll try my best to make it clear so that you can do it by yourself in the future.

If you're converting from degrees to radians, multiply by

\frac{\pi}{180^*}

If you're converting from radians to degrees, multiply by

\frac{180^*}{\pi}

Let's try some examples.

15º= 15(\frac{\pi}{180} )=15/5(\frac{\pi}{180/5} )=\frac{3\pi}{36} =\frac{1\pi}{12}=\frac{\pi}{12}

70º=70(\frac{\pi}{180} )=70/10(\frac{\pi}{180/10})=7(\frac{\pi}{18})=\frac{7\pi}{18}

300º=300(\frac{\pi}{180} )=300/10(\frac{\pi}{180/10})=30/6(\frac{\pi}{18/6})=5(\frac{\pi}{3})=\frac{5\pi}{3}

--------------------------------------------------------------------------------------------

\frac{4\pi}{3} radians=\frac{4\pi}{3}( \frac{180}{\pi} )=\frac{4\pi}{3/3}( \frac{180/3}{\pi} )=4(60)=240 degrees (add '' º '')

\frac{11\pi}{12} =\frac{11\pi}{12}(\frac{180}{\pi})=\frac{11\pi}{12/12} (\frac{180/12}{\pi})=11(15)=165

\frac{\pi}{8} =\frac{\pi}{8}(\frac{180}{\pi})=\frac{\pi}{8/4}(\frac{180/4}{\pi})=\frac{1}{2}(45)=22.5 or 23

Write an equation to solve each problem and then solve it. b In a 3-digit number, the hundreds digit is four more than the ones
Misha Larkins [42]

Answer:

digits are: 0, 4, 8. The required number is: 480.

Step-by-step explanation:

→ Let ones digits is 'x', then according to the condition the hundreds digit is 'x+4', and the tens digit is '2(x+4)'.

→ According to the condition the sum of the digits is: x+(x+4)+2(x+4)=12.

→ After evaluation this equation, x=0 - this is ones digit;

→ x+4=0+4=4 - this is hundreds digit;

→ 2(x+4)=2(0+4)=8 - this is ten digit.
