What areC12, C31, and C22 of matrix C?
Liono4ka [1.6K]

Compute the sum to simplify C :

C = \begin{bmatrix}16-0.5 & 9+0 \\ -3+5 & 0 + 8 \\ 4-3 & -10+14\end{bmatrix} = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ 1 & 4\end{bmatrix}

Now, c_{ij} is the entry of the matrix in row i and column j, so

C = \begin{bmatrix}15.5 & \boxed{9} \\ 2 & 8 \\ 1 & 4\end{bmatrix} \implies c_{12} = 9

C = \begin{bmatrix}15.5 & 9 \\ 2 & 8 \\ \boxed{1} & 4\end{bmatrix} \implies c_{31} = 1

C = \begin{bmatrix}15.5 & 9 \\ 2 & \boxed{8} \\ 1 & 4\end{bmatrix} \implies c_{22} = 8

SV−→bisects ∠RST. If m∠RSV = 64, what is m∠RST?
Anuta_ua [19.1K]

Given:

\overrightarrow{SV} bisects ∠RST.

m\angle RSV=64^\circ

To find:

The m\angle RST.

Solution:

Since, \overrightarrow{SV} bisects ∠RST, therefore

m\angle RSV=m\angle VST         ...(1)

Now,

m\angle RST=m\angle RSV+m\angle VST

m\angle RST=m\angle RSV+m\angle RSV         [Using (1)]

m\angle RST=2\times m\angle RSV

m\angle RST=2\times 64^\circ              [\text{Given }m\angle RSV=64^\circ]

m\angle RST=128^\circ

Therefore, the value of m\angle RST is 128^\circ.
