Dendritic
The nile is trellis
trellis as the tributaries meet at approximately right angles
The Amazon River is an example of dendritic drainage, which resembles the branching pattern of tree roots. Dendritic drainage patterns are common in areas with uniform rock structure and slope, where rivers and streams flow in multiple directions.
The Amur River features dendritic drainage. This pattern of river system resembles the branching of tree roots and is common in areas with homogenous rock structures, where water flows in a branching pattern towards lower elevations.
I would say Trellis because it doesn't look dendritic, but I can't be sure.

describe the dendritic and trellis drainage pattern?
Dendritic drainage patterns are tree like while trellis drainage patterns are formed when tributaries meet at right angles so they look like squares or rectangles.
The amazon river is probably a trellis because it has 2 types of alternating soft and hard rocks. A trellis drainage is the rectangular drainage pattern created if rivers flow through alternating bands of hard and soft rocks.
The St. Lawrence River drainage system exhibits dendritic drainage, characterized by a network of streams that resemble tree branches. This pattern is typical of regions with uniform rock types and gradual slopes, allowing water to flow in a tree-like pattern towards the river.
The Mississippi river is a dedentric drainage
