Answer:

(-3,-10)

Step-by-step explanation:

The reason is because we need to plug in the values into the equation:

3(-3) - 3(-10) = 21

-9 +30 = 21

21 = 21

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.
