4,56 км / ч просто разделят ускорението и точката на среща.
Answer:
x= 16
/20420505
Step-by-step explanation:
Let's solve your equation step-by-step.
5(215)x=16
Step 1: Simplify both sides of the equation.
20420505x=16
Step 2: Divide both sides by 20420505.
20420505x
/20420505 = 16
/20420505
x= 16
/20420505
X is 66 degrees, you just subtract 24 to 90 and it gives you 66.
