Answer:
m<A = 39* b = 26.6 a = 16.9
Step-by-step explanation:
so lets start with m<A, with that we would just need to add m<B and m<C and subtract the sum from 180.
and onwards to the side lengths
we would need to establish that sinA / a = sinB / b = sinC / c.
with that out of the way, we know m<C and c so we would divide the sine of m<C by c and use algebra to find b with the equation
b = sinB / (sinC / c)
and we can use this to find a
a = sinA / (sinC / c)
im sorry to say but i couldn't find a simpler answer so this should do
