1.

Use the inverse trig function to find all the missing angles. (If needed round your answers to the nearest tenths place.)

sin Z = 0.8387

∠Z = °

sin U = 0.6561

∠U = °

cos U = 0.8480

∠U = °

tan A = 1.0724

∠A = °

cos Y = 0.3420

∠Y= °

tan θ = 2.1445

∠θ= °

You have right triangle ABC with the right angle at C.

You're given:

  • Side AC = 9 units

  • Side BC = 12 units

  • Angle C = 90°

🔍 Tasks:

  1. Find the length of AB (the hypotenuse).

  2. Find angle A (rounded to the nearest tenth of a degree).

  3. Find angle B (rounded to the nearest tenth of a degree).
