Answer 1

Sine angle A = 2.2 / 2.6
sine angle A = 0.8461538462
angle A = arc sine (0.8461538462)
angle A = 57.796 Degrees

cosine angle B = 2.2 / 2.6
cosine angle B = 0.8461538462
angle B = arc sine (0.8461538462)
angle B = 32.204 Degrees

AC^2 = 2.6^2 - 2.2^2
AC^2 = 6.76 -4.84
AC^2 = 1.92
AC = 1.3856406461
