WebWe just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c 2 + a 2 − b 2 2ca WebFinal answer. Step 1/3. Value of chi square distribution for α = 0.005 for 5 degrees of freedom is 16.749. Explanation. To obtain critical value corresponding to α = 0.005 for degree of freedom 5 look for value corresponding to ν = 5 and α = 0.005 in probability distribution table of chi square distribution. View the full answer. WebThe sum of the squares of a and b is a 2 + b 2. We could obtain a formula using the known algebraic identity (a+b) 2 = a 2 + b 2 + 2ab.
