Answer:
Step-by-step explanation: 5 17 7 22
the long leg would be opposite the middle angle 60°, the hypotenuse is opposite the 90° angle thus leaving the 30° is opposite the short leg
1) use sin Θ = opp / hyp sin 60° = 12 / hyp to find the hypotenuse
1) use sin Θ = opp / hyp sin 30° = opp/ hyp to find the short leg
hyp = 12 / sin(60) = 13.856 hypotenuse
opp = (12 / sin(60)) (sin 30) = 6.92 short leg
short leg ² + long leg ² = hypotenuse ²
48 + 144 = 192 sum of the legs squared = hyp²
