j = -56
Step-by-step explanation:
j - 39 = -95
Add 39 to both sides:
j - 39 = -95
+ 39 + 39
j = -56
Final answer: j = -56

Answer:
1 x 0.28 works, along with 5 x 0.056.
Solving for the angles, we need to apply and use Law of Cosines:
Solving for ∠AB, we have
cos ∠AB = (BC² + CA² - AB²) / 2*BC*CA
cos∠AB = (9²+17² -13²) / 2*17*9
∠AB = 48.94°
Solving for ∠BC, we have
cos ∠BC = (AB² + CA² - BC²) / 2*AB*CA
cos∠AB = (13²+17² -9²) / 2*17*13
∠BC = 31.47°
Solving for angle CA, we have:
∠CA = 180° - 31.47° - 48.94°
∠CA = 99.49°
The smallest angle is 31.47°.
