Answer:
1. 74.6° = m∠C 65.4° = m∠A a = 2.83
2. Triangle does not exist
Step-by-step explanation:
1. Use the law of sines to find m∠C
sin 40/2 = sin C/3
3sin 40/2 = sin C = .96418...
arcsin .96418... = 74.6° = m∠C
m∠A = 180 - 40 - 74.6 = 65.4°
a/sin 65.4 = 2/sin 40
a = 2 sin 65.4/sin 40 = 2.83
2. sin 95/4 = sin C/5
5sin 95/4 = sin C = 1.2452... which is impossible since the cosine of an angle is ≤ 1
Well, if it is based off the Pythagorean Theorem, here is the formula: a squared plus b squared equals c squared. It also works with c squared minus a squared equals b squared. I hope this helps! Please mark me brainliest!

Answer:
102 yards.
Step-by-step explanation:
If she walked 30 yards and 72 all you have to do is add them together wich is 102 yards. If thats how far she walked in all she probably walked the same length back unless she took a longer way or a short cut.
I hope this helps!
