Answer:
<h3>-π/12</h3>
Step-by-step explanation:
Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12
180 degrees = πrad
-15 degrees = x
Cross multiply
180x = -15π
x = -15π/180
x = -π/12
Hence the value of -15 degrees in radians is -π/12
Yes 54 is greater then 45!
The answer would be 2.3x10^2.
I'm guessing the power series given is

which you can condense somewhat into

You should recognize this as a geometric series, which converges for
