Answer:

The answer is actually 3

Step-by-step explanation:

The two triangles are drawn to scale, so we can use the scale factor of \maroonD{1\dfrac{1}{2}}1

1

start color #ca337c, 1, start fraction, 1, divided by, 2, end fraction, end color #ca337c to find \greenD{x}xstart color #1fab54, x, end color #1fab54.

Hint #22 / 3

\begin{aligned} [\blueD{\text{length on A}}] \cdot [\maroonD{\text{scale factor}}] &= [\greenD{\text{length on B}}]\\\\ \blueD{2}\cdot \maroonD{1\dfrac{1}{2}}&=\greenD{x} \\\\ \greenD{3}&=\greenD{x} \end{aligned}

[length on A]⋅[scale factor]
