My Work/Reasoning:
First we find the sum of 1/3 and 1/5.
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal.
Finally, we simplify.
Which fraction is equivalent to 63/9 ? PLS HELP!! thxs =)

Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
=
, substitute values
=
( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b = ≈ 9.5 ( to the nearest tenth )
Also
=
=
( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c = ≈ 14.7 ( to the nearest tenth )
