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
Answer:
9 ft, 28 ft, 26 ft
Step-by-step explanation:
The perimeter is the sum of side lengths, so ...
P = a + b + c
63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths
63 = 7n . . . . . . simplify
9 = n . . . . . . . . divide by 7
4n -8 = 36 -8 = 28 . . . . second side length
2n +8 = 18 +8 = 26 . . . . third side length
The side lengths are 9 ft, 28 ft, 26 ft..
