Question

Which benchmark angles (multiples of 30º or 45º) are closest to the rotation angles below? CHOOSE ALL THAT APPLIES



a. 40º  b. 140º    c. 175º                                                             

d. 220º e. 250º  f. 310º

Answer 1

a,c,d and f just because of the multiples of 30 and 45

Answer 2

Answer:

a,c,d and f  are correct

Step-by-step explanation:

Benchmark angles are the angles  that are multiples of either 90°, 45° or 30°. Here multiple of only 30 and 45 are asked. So, among the options those angles which are common multiples of 30°and 45° must be the answers.

here options a,c,d and f  are correct.
