Answer:
5/12
Step-by-step explanation:
12 total squares
5 shaded
5shaded to 12 total
5:12
or
5/12
The answer is the product of 3 and the product of 4 and 12
Y=13 Because a line equals 180. 180-11=169/13=13
x=8 because 180+22=202-4=198/11=18
Answer:
tan (A-B) = ± 4/3
Step-by-step explanation:
COS (A-B) = 3/5
COS² (A-B) = (3/5)² = 9/25 = 1 - sin² (A-B)
sin² (A-B) = 1 - 9/25 = 16/25
sin (A-B) = ± 4/5
tan (A-B) = sin (A-B) / cos (A-B) = (± 4/5) / (3/5) = ± 4/3
