(a) γ is easy, since the angles sum to 180°
Then use law of sines to find b,c
(b) this is a right triangle. a^2 = b^2+c^2
then just use the trig functions to get the other two angles.
(c) use the law of cosines to get any or all of the angles. Or, having one, you can use the law of sines to get the others.
Using trigonometric ratios find the remaining side lengths and angle measurements to 2 decimal places each:
(a) α = 35°, β = 90°, a = 30
(b) α = 90°, b = 7, c = 6
(c) a = 33, b = 56, c = 65
