You could also use the Law of sines to find the angle at right center  ....then use the law of sines AGAIN to calculate 'x ft '  ( knowing there are 180 degrees in a triangle to find angle at 3rd base)       you will get the same answer:  3*0.0 ft        Let me know what you find ' * ' to be when you calculate it !

You are looking for  '  x ft '  in the diagram......

You could use the Law of Cosines     You know two sides of the triangle    90 ft  and  339.4 ft    and you know angle 63.4

c²  = a²  + b² -2a b Cos (angle C)          

c = 339.4       a = 90    b= x ft   angle C = 63.4      Plug and Play !

You left out some information in your question....

See:

https://web2.0calc.com/questions/suppose-20-of-all-widgets-produced-at-a-factory-are-defective

Whichever scenraio gets closest to finding 20 %  defective is the closest to reality....

A  5/100 =  5%

B  5/50 = 10%

C 5/25 = 20%

D 5/20 = 25 %           C

True!

The three lines all intersect at this point   2,5

v_f =v_o + at       a = -9.8 m/s^2

Vertical velocity is   5.42 m/s sin 65 = v_y = 4.912 m.s

  When velocity = 0   it is at the max height

0 = 4.912 - (9.8) t     t= 1/2 sec

No, Michael is incorrect......the second 25% is taken off of the reduced price....not the original price:

Manager's way:   495 - 20% = 396       396 - 25% =  $ 297

Michael's way      495 - 45% =  $ 272.25

Hmmmmm.....   wouldn't it be 14 toppings?

14 c 2 = 91

PLUS   14 single toppings = 105    PLUS NO TOPPING = 106.
