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 $128^\circ$ .

Quadrilateral FRIO is the result of a reflection of quadrilateral LAMB over the y-axis. FRIO has vertices at F(-7,6), R(1,7), I(

andrew11 [14]

Answer:

F' = (7, 6)

R' = (-1, 7)

I' = (-2, -5)

O' = (6, -6)

Step-by-step explanation:

The rule of reflection over the y-axis is, (x, y) ---> (-x, y). So change all the x values into the opposite signs. So the -7 of F would turn into just 7, the 1 of R would turn into -1, the 2 of I would turn into -2, and -6 of O would turn into just 6.
