Answer: A toy airplane costs $6
Step-by-step explanation: Because 4 toy cars cost $8 , then there are $30 for 5 toy planes. One toy plane cost 30/5 = $6
X= -2 and x= 2 are the answers
The interior angles sum to 180°, so the missing angle has measure
180° - 106° - 12° = 62°
Use the law of sines to find RS:
sin(106°)/RS = sin(62°)/34 ⇒ RS = 34 sin(106°)/sin(62°) ≈ 37
