In triangle ABC, angle C is a right angle. Find the remaining sides and angles. Round your answer to the nearest tenth.
angle B = 52 degrees, b = 10

  • geometry - ,

    Since A+B+C = 180°, A = 38°

    If you haven't had trig yet, it will be tough to calculate the other sides.

    a = 10 tan 38° = 7.8
    c^2 = a^2 + b^2 = 100 + 61 = 161
    c = 12.7
