Question

Solve for the remaining angles. http://tinypic.com/r/23sej5g/5

Answer 1

So I already got angle A which is 33.54º. How do I get the other two? What do change in my equation?

Answer 2

\[cosA = \frac{ 442.85^{2}+255^{2}−270^{2} }{ 2(442.85)(255) }\]
What about the two below?
\[cosB = ?\]\[cosC = ?\]

Answer 3

I used this equation to find A. \[cosA = \frac{ b ^{2} + c ^{2} - a ^{2} }{ 2bc }\]

Answer 5

Just rearrange the letters

\[\cos B = \frac{a^2 + c^2 - b^2}{2ac}\]
