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
Your answer would be A 1040.
Answer:
-4 2/21
Step-by-step explanation:
-2 3/7 - 1 2/3
Change to improper fraction
-2 3/7 = -17/7
- 1 2/3 =-5/3
-17/7-5/3
L.C.M=21
-51-35/21
= -86/21
= -4 2/21
