1 answer:

8 0

Answer: C) 0

You can use a calculator to get this answer, a reference table, or the unit circle. The angle pi radians is equivalent to 180 degrees. Note how the point on the unit circle corresponding to 180 degrees is (1,0). This point has a y coordinate of zero. More broadly, y = sin(theta) where theta is the angle.

Consider △RST and △RYX.

Answer:

B. StartFraction R Y Over R S EndFraction = StartFraction R X Over R T EndFraction = StartFraction X Y Over T S EndFraction

i.e $\frac{RY}{RS}$ = $\frac{RX}{RT}$ = $\frac{XY}{TS}$

Step-by-step explanation:

Two or more shape or figures are similar when their sides and angles can be compared appropriately.

In the given figure, ΔRXY is within ΔRST. Since the two triangles are similar, then their length of sides can be compared in the form of required ratios.

So that by comparison,

$\frac{RY}{RS}$ = $\frac{RX}{RT}$ = $\frac{XY}{TS}$

Therefore, the correct option to the question is B.
