ABCDEF - QRSTUV. Find the length of ST.
labwork [276]

Answer:

Option (1)

Step-by-step explanation:

It's given in the question, ABCDEF ~ QRSTUV,

Their corresponding sides will be proportional.

\frac{AB}{QR}= \frac{BC}{RS}= \frac{CD}{ST}= \frac{DE}{TU}= \frac{EF}{UV}

Now we choose \frac{DE}{TU}=\frac{CD}{ST}

From the figure attached,

\frac{6}{2.4}=\frac{5.4}{ST}

ST = \frac{5.4\times 2.4}{6}

ST = 2.16

Therefore, Option (1) is the correct option.

I need help ASAP, please save me.
Sav [38]

Answer:

Angle DCE is a central angle so it's equal to the arc facing it, which is DE, which is given as 116. So angle DCE= 116°

Angle EDF is an angle between a tangent line, DF, and a secant line, DE. So its measure is equal to half of the arc it surrounds, which is arc DE. 116/2= 58°. Angle EDF=58°.
