Consider the triangle which has
a=4, b=7 and c=8
Find the measure of angles ∠A=, ∠B= and ∠C= Give your answer in degrees to at least 3 decimal places.
Step 1)
we know that according to law of cosine,
Hence,
we have a = 4, b = 7 and c = 8 hence,
Hence,
rounding to the three decimal places we can say that,
Step 2)
we know that according to law of cosine,
Hence,
we have a = 4, b = 7 and c = 8 hence,
Hence,
rounding to the three decimal places we can say that,
Step 3)
we know that according to law of cosine,
Hence,
we have a = 4, b = 7 and c = 8 hence,
Hence,
rounding to the three decimal places we can say that,
