The measurement could be the value, 38 degrees, or it could be the actual act of measuring the angle.
By keeping Ur eyes perpendicular to the vernier and main scale while taking the measurement.
there is special instrument named "angle distribution measuring system" for the divergence angle measurement of LEDs. my email: bkk2003@163.com
38
It is degree Celsius, or degree Fahrenheit, or degree Kelvin or Rankine
A degree is the measure of an angle.
An acute angle
A right angle
An angle of 343 degrees is a reflex angle
100
abtues
A 110 degree angle is obtuse.
18 degrees
1.269
90 - 38 = 52 degrees.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 38 degree angle is equal to 180 - 38 = 142 degrees.
The whole measurement of a angle.
I need to know how to find each angle measured to the first degree. Such as: Sin B= 0.4848
