    tan(x) = 6/11

    tan⁻¹(6/11) = 28.6° answer//

    Smallest angle is opposite smallest side and it is arctan(6/11) = 28.6 degrees to the nearest tenth

    Units are [''].

    Legs are AC = b = 11 and AB = c = 6.

    a^2 = b^2 + c^2, ie., a^2 = 11^2 + 6^2 = 157.

    Clearly, the smallest angle in the triangle will be

    opposite the smaller arm which is c.

    Law of cosines gives c^2 = a^2+b^2-2ab*cos(C).

    ie., cos(C) = (a^2+b^2-c^2)/2ab.

    Here, cos(C) = (157+121-36)/[2*11rt157] =

    121/(11rt157) = (11/rt157) = 0.8778955729 and

    C = arccos (0.8778955729) = 28.61045967°

    = 28.6° to nearest tenth of a degree.

  • tan(t) = 6/11

    t = arctan(6/11)

    t = ‭28.610459665965216957704244177375‬...
