6. Find the value of x. 120 6x

Virty [35]

Both angles are vertical angles. According to the Vertical Angles Theorem, vertical angles are congruent. Therefore:
6x°=120° [Vertical Angles Theorem (vertical angles are Congruent)].
6x/6=120/6 [Division P.O.E]
x=20.

Therefore, if x=20, then:
6(20)=120 [Substitution P.O.E.
120=120 [Symmetric P.O.E]

And thus,
x=20

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

$=\frac{65}{100}*80*100\\\\= 65*80\\= 5200$

Amount paid for next 50 watches = (55% of 80) * 50

$= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200$

Remaining watches = 280 -(100+ 55)

= 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

$= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500$

Amount received by the watch maker = 5200 + 2200 + 4500

= £ 11900
