Step 1 Write the numerical value of measure of angle given in degrees Step 2 Now, multiply the numeral value written in the step 1 by π/180 Step 3 Simplify the expression by cancelling the common factors of the numerical Step 4 The result obtained after the simplification will beA reference angle is the acute version of any angle determined by repeatedly subtracting or adding straight angle (1 / 2 turn, 180°, or π radians), to the results as necessary, until the magnitude of the result is an acute angle, a value between 0 and 1 / 4 turn, 90°, or π / 2 radians For example, an angle of 30 degrees has a reference angle of 30 degrees, and an angle of 150 degrees also has a reference angle of 30 degreesStart studying Pre Calculus Radians and Degrees Learn vocabulary, terms, and more with flashcards, games, and other study tools
