Answer:

AA Similarity Postulate  proves △FWJ∼△PKJ

Step-by-step explanation:

It is given that,

△FWJ and △PKJ are two right angled triangle.

In △FWJ right angled ate W  and in △PKJ right angled at K.

Therefore <W = < K

<u>To find angles of ΔFWJ</u>

In △FWJ , <FJW = 63°  then <WFJ = 90° - 63° = 27°∼△PKJ

<u>To find angles of ΔPKJ</u>

In △PKJ, <JPK = 27° then <PJK = 90°-27° = 63°

According to this information AA Similarity Postulate  proves that

△FWJ∼△PKJ

in an election between two candidates one got 55% of the total valid votes 20% votes were invalid if the total number of votes w
timurjin [86]

Answer:

25%- 1875 Votes

<em>7500 x 0.55 = 4125  (</em><em>first candite valid votes</em><em>)</em>

<em>7500 x 0.20 = 1500 (</em><em>invalid</em><em>)</em>

<em>first candite valid votes</em><em> </em><em>(</em><em>55</em><em>) + invalid votes (</em><em>20</em><em>) = 75% of total votes </em>

<em>first candite valid votes</em><em> </em><em>(</em><em>4125</em><em>) + invalid votes (</em><em>1500 </em><em>) = 5625 of total votes </em>

<em />

<em>100 (</em><em>total</em><em> </em><em>percent of votes</em><em>) - 75 (</em><em>total percent of votes</em><em>) = 25% Votes Left</em>

<em>7500 (</em><em>total</em><em> </em><em>number of votes</em><em>) - 5625 (</em><em>total number of votes</em><em>) = 1875 Votes Left</em>

<em>7500 x 0.25 = 1875 (</em><em>valid votes for the other candite</em><em>)</em>
