Answer:
A
Step-by-step explanation:
We require to find ∠ A
Subtract the sum of the given angles from 180
∠ A = 180° - (85 + 53)° = 180° - 138° = 42°
Using the Sine rule in Δ ABC, that is
= 
, that is
= ( cross- multiply )
AC × sin42° = 85 × sin85° ( divide both sides by sin42° )
AC = 
≈ 126.6
Answer:
C
Step-by-step explanation:
Three thousand divided by 14.66 gives you 204.638. Round it to 204 and there ya go.
20.8478066 (or 20.85%)
you do 480.77 minus 380.54 and it comes out to 100.23 and then you do 100.23/480=x/100 (discount/original=percent/100) and you multiply 100.23 by 100 and it comes to 10023 and you do 10023 divided by 480.77 and it comes out to 20.8478066 or 20.85%
8.275
8.28 is the estimated answer
