Answer:
x = 12
Step-by-step explanation:
Hello!
The sum of 3x - 16 and 1 gives us 2x - 3.
<h3>
Solve for x</h3>
- 3x - 16 + 1 = 2x - 3
- 3x - 15 = 2x - 3
- x - 15 = -3
- x = 12
The value of x is 12.
The fundamental definition of a radian: take a piece of string as long as the radius of a circle, and bend it round the circumference, The angle it subtends at the centre is a radian.
<span>Because you need 2*pi radii to to go all round a circle, it follows that 2*pi radians = 360 degrees; 1 radian = 180/pi degrees. </span>
<span>An arc length L subtends an angle (L/r) radians where r is the radius of the circle.</span>
