Answer:

A, E

Step-by-step explanation:

Remember SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Therefore, we can say:

sin 20° = LN / 8

cos 70° = LN / 8

tan 70° = MN / LN

Only the first and last options are correct.

Let \mathbf V be the m\times3 matrix whose columns are \mathbf v_1,\mathbf v_2,\mathbf v_3, and let \mathbf c be the vector whose components are the constants c_1,c_2,c_3. Now consider the matrix equation

\mathbf V\mathbf c=\mathbf 0


Multiplying both sides by \mathbf V^\top, we have

\mathbf V^\top(\mathbf V\mathbf c)=(\mathbf V^\top\mathbf V)\mathbf c=\mathbf 0

More explicitly, we're writing

\mathbf V=\begin{bmatrix}\mathbf v_1&\mathbf v_2&\mathbf v_3\end{bmatrix}

Multiply both sides by \mathbf V^\top and the left hand side can be written as

\mathbf V^\top\mathbf V=\begin{bmatrix}{\mathbf v_1}^\top\\{\mathbf v_2}^\top\\{\mathbf v_3}^\top\end{bmatrix}\begin{bmatrix}\mathbf v_1&\mathbf v_2&\mathbf v_3\end{bmatrix}=\begin{bmatrix}{\mathbf v_1}^\top\mathbf v_1&{\mathbf v_1}^\top\mathbf v_2&{\mathbf v_1}^\top\mathbf v_3\\{\mathbf v_2}^\top\mathbf v_1&{\mathbf v_2}^\top\mathbf v_2&{\mathbf v_2}^\top\mathbf v_3\\{\mathbf v_3}^\top\mathbf v_1&{\mathbf v_3}^\top\mathbf v_2&{\mathbf v_3}^\top\mathbf v_3\end{bmatrix}

We're told that {\mathbf v_i}^\top\mathbf v_j=0 whenever i\neq j, so we're left with

\mathbf V^\top\mathbf V=\begin{bmatrix}\|\mathbf v_1\|^2&0&0\\0&\|\mathbf v_2\|^2&0\\0&0&\|\mathbf v_3\|^2\end{bmatrix}

Each of \mathbf v_1,\mathbf v_2,\mathbf v_3 are nonzero, which means their norms are nonzero, which necessarily implies that \mathbf c=0, and so the vectors \mathbf v_1,\mathbf v_2,\mathbf v_3 must necessarily be linearly independent.
