填空题 下列事件过程的功能是：建立一个名为Data1的随机文件，存放角度值及这些角度的正弦函数值和余弦函数值，角度为1，2，3，…，90。请在空白处填上合适的代码，将程序补充完整。
Private Type Ang
K As Integer
Sinx As Single
Cosx As Single
End Type
1"定义Ang类型的变量Ksc
Private Sub Form_Click()
Dim Y As Single
Open "C:/Data1.txt"For Random As #1 Len=10
Put #l, 1, Ksc
Y=3.14159/180
For i=1 To 90
Ksc.K = i
2 = Sin(i * Y)"给变量Ksc的正弦函数值赋值
Ksc. Cosx=Cos(i * Y)
Next i
Close #1
End Sub
