Answer:
B i think let me solve
Step-by-step explanation:
The number next to a variable, for example: 5x, is called a coefficient. And all you do is multiply the number with the variable
The answer is c, 6/9, because 0.75 equals 3/4 in fraction form, and 6/9 reduces to 2/3.
Answer:
150 cause subtract 150 from 270 you get 150
Step 1: Convert , which is in radians into degrees. To convert it multiply by
900/12
75
Step 2: 75 degrees isn't on the unit circle but 45 degrees and 30 degrees is. Since 45 + 30 = 75 you can use the cosine of 45 and 30 to find the exact value
cos45 =
cos30 =
Step 3: Add the cos45 and cos30 to get cos5pi/12
Hope this helped!
