Answer:
x = 20 degrees.
Step-by-step explanation:
cos40∘=sin(x+30∘)
sin (x + 30) = 0.766
x + 30 = arcsin 0.766 = 50
x = 50 - 30 = 20.
Step-by-step explanation:
1. YES
2. YES
3. YES
4. NO
this is a decimal that neither terminates nor repeats.
9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
The answer would be 0.37.
