To find AB(x) and BC(y), you can do(there are multiple ways you can do this):
tan A = 
tan 60° =
or (tan 60°) · 7 = y
tan 60° = 
√3 · 7 = y
7√3 cm = y
sin B = 
sin 30° =
or 
sin 30° =
= 
x = 
x = 14 cm
AB = 14cm
BC = 7√3 cm
Answer:
0.39
Step-by-step explanation:
think about it this way, if you take away the decimal it would be 39 and 04. 04 is another way to write 4 and 4 is less than 39. so 0.04 is less than 0.39
Multiply 45 degrees and 72 degrees
It should be 15% I think I’m right
