Answer: 78 and 6/7
Step-by-step explanation:
Vertically, horizontally, and diagonally,
As the sine rule states,
A/sina = B/sinb = C/sinc .
in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.
there are:
side a, with angle â .
side b, with angle b.
so the answer is C.
if you input these into the sine rule, it would be:
a/ sin a = b/sin b
I don't understand it. Explain more.
