Side a, angle B and angle C of triangle ABC are 26.6 units, 61.9 degrees and 8.1 degrees respectively.
Given that;
First we determine the length of side a
[tex]a = \sqrt{b^2-c^2-2bc*cos(A)}[/tex]
We substitute our values into the above equation[tex]a = \sqrt{25^2-4^2-(2*25*4*cos(110)}\\\\a = 26.6[/tex]
Side a has a length of 26.6 units.
[tex]B = cos^{-1}(\frac{a^2+c^2-b^2}{2ac}) \\\\B = cos^{-1}(\frac{26.63464^2+4^2-25^2}{2*26.63464*4}) \\\\B = 61.9[/tex]
Angle B is 61.9 degrees.
[tex]C = cos^{-1}(\frac{a^2+b^2-c^2}{2ab} )\\\\C = cos^{-1}(\frac{26.63464^2+25^2-4^2}{2*26.63464*25} )\\\\C =8.1[/tex]
Angle C is 8.1 degrees.
Therefore, side a, angle b and angle c of the triangle ABC are 26.6 units, 61.9 degrees and 8.1 degrees respectively.
