the sum of complimentary angles equal 90°.
x + 58° = 90°
x = 32°
cos (32°) = 0.848
Answer: B
Note: you can also take sin (58°) to get the answer.
Answer:
Option b is correct!
Step-by-step explanation:
cosine of complimentary angle to 58 is
complimentary of 58 means = 90 -58 = 32 [ since sum of complimentary angles is 90 degrees ]
so its asking for cos (90-58) = cos 32 which equals 0.848 or 0.85
therefore option b ( 0.85 ) is correct!
