Given: <br><br>EM, EQ-secants<br><br>Prove: MP·EW=WQ·EP
Dennis_Churaev [7]

Answer:

Step-by-step explanation:

A secant is a straight line from a point outside a given circle that passes through two points on its circumference.

From the given diagram, EM and EQ are secants.

Thus,

<PEW ≅ <WEP    (common angles)

<EMP ≅ <EQW (secant-chord theorem)

<WMP ≅ <PQM (inscribed angles of arc WP)

Therefore,

\frac{EW}{WM} = \frac{EP}{PQ}   (corresponding sides of a triangle)

This implies that,

EW*PQ = EP*WM

Therefore,

MP*EW = WQ*EP  (properties of a similar triangle)

Using the greatest common factor 4/9 x 3/8
KIM [24]

Answer:

1/6

Step-by-step explanation:

4/9&3/8

4/9x3/8= ?

Multiply both numerators

= 4 x 3

= 12

Multiply both denominators

= 9 x 8

= 72

Use above values of step 2 & 3, and rewrite as below

= 12/72

so, 12/72 is equivalent to the fraction for 4/9 times of 3/8, and its simplified form is 1/6.
