### Linear Transformation Problem

**Problem Statement:**

3) Let \( T : \mathbb{R}^2 \rightarrow \mathbb{R}^3 \) be the linear transformation such that 
\[ T(<1,2>) = <1,1,1> \]
and
\[ T(<2,3>) = <0,2,5> \]

**Tasks:**

a) Find the standard matrix for \( T \).

b) Find a basis for the orthogonal complement of the range of \( T \).

**Solutions:**

For part (a), we need to determine the standard matrix \( [T] \) of the linear transformation \( T \). The matrix can be found by determining how \( T \) maps the standard basis vectors of \( \mathbb{R}^2 \).

For part (b), to find a basis for the orthogonal complement of the range of \( T \), we first need to find the range space of \( T \) and then determine its orthogonal complement within \( \mathbb{R}^3 \).

**Steps for part (a)**:

1. Express the given transformation conditions in matrix form.
2. Solve the system of equations to find the matrix representation of \( T \).

**Steps for part (b)**:

1. Determine the range of \( T \).
2. Find the orthogonal complement of the range within \( \mathbb{R}^3 \).
