Question

reflect the vector $\langle -3,5 \
angle$ across the x - axis.

Explanation:

Step1: Recall reflection rule

When reflecting a vector \(\langle x,y
angle\) across the \(x\) - axis, the rule is \(\langle x,y
angle
ightarrow\langle x, - y
angle\).

Step2: Apply the rule

Given the vector \(\langle - 3,5
angle\), using the rule \(\langle x,y
angle
ightarrow\langle x, - y
angle\) with \(x=-3\) and \(y = 5\), we get \(\langle-3,-5
angle\).

Answer:

\(\langle-3,-5
angle\)
