First, you must find the difference between 320 and 380.
The difference is 60.
Then you may want to know what percentage o 320 is 60 that is increased that way.
So divide 60 to 320 (60/320).
Then the answer is .1875 then multiply it to 100 to get the percentage and it will be 18.75% .

Please help me out :)
arlik [135]

Answer:

\frac{\sqrt{17} }{7}

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sinx = \sqrt{1-cos^2x}

Note that (\frac{4\sqrt{2} }{7})² = \frac{32}{49}

sinΘ = \sqrt{1-(32/49)}

        = \sqrt{\frac{17}{49} } = \frac{\sqrt{17} }{7}
