The triangle ABC determines the size of the sides a and b and the magnitudes of the interior angles β and γ, given c = 1.86 m, the line on the side c is 2.12 m, and the angle alpha is 40 ° 12 '.

Correct answer:

a =  1.7865 m
b =  2.7436 m
β =  97.576 °
γ =  42.224 °

Step-by-step explanation:

Our quadratic equation calculator calculates it.

β=π180°arccos(2 a ca2+c2b2)=π180°arccos(2 1.7865 1.861.78652+1.8622.74362)=97.576=97°3434"
