`(S): (x+1)^2 + (y-2)^2 + (z-3)^2 = 25 \Rightarrow I(-1; 2; 3), R = 5`

`T(-1; 2; -10) \Rightarrow IT = 13`

`TP = \sqrt{13^2 - 5^2} = 12`

`t_1 = 12 / 4 = 3`

`\cos(TIP) = 5 / 13 \Rightarrow TIP \approx 67,38^{\circ}`

`M(-1; -3; 3) \Rightarrow IM = 5 = R`

`\cos(TIM) = 0 \Rightarrow TIM = 90^{\circ}`

`MIP = 90^{\circ} - 67,38^{\circ} = 22,62^{\circ}`

`s = (\pi \cdot 5 \cdot 22,62) / 180 \approx 1,974`

`t_2 = 1,974 / 1,5 \approx 1,32`

`t = 3 + 1,32 = 4,32`
