First, we will calculate the hypotenuse of the first triangle
[tex]\begin{gathered} \cos 51=\frac{11}{h} \\ h=\frac{11}{\cos51} \\ h=17.48 \\ \end{gathered}[/tex]Now let's calculate the angle a
[tex]\begin{gathered} a=180-64-54 \\ a=65 \end{gathered}[/tex]Total result
T = 17.48+12.204+2.62+4.72
T = 37.024
The answer would be 37.024
for all triangles input data entered: side a, b and angle γ.
Calculation of the third side c of the triangle using a Law of Cosines
[tex]c^2=a^2+b^2-2ab\cos \gamma[/tex]
