Answer: Choice C

x = sqrt(12)

y = 18

=======================================

Triangle TRU is a 30-60-90 triangle

RU = 4 is the hypotenuse

UT = 2 is the short leg and half the hypotenuse

RT = long leg

RT = (short leg)*sqrt(3)

RT = 2*sqrt(3)

x = 2*sqrt(3)

x = sqrt(4)*sqrt(3)

x = sqrt(4*3)

x = sqrt(12)

-----------

Angle TRS is 30 degrees

y+12 = 30

y = 30-12

y = 18

never [62]

Answer:

-4 chickens.

-8 beef plates

Step-by-step explanation:

Let x denote a chicken dish and y denote a beef dish.

-Assume that every member only had one dish of either chicken or beef.

#The problem is then represented as:

$x+y=12, =>x=12-y\ \ \ \ \ \ ...i\\\\10x+14y=136\ \ \ \ \ \ \ \ \ ...ii\\\\\#substitute \\10(12-y)+14y=136\\\\120-10y+14y=136\\\\2y=16\\\\y=8\\\\\therefore x=12-8=4$

Hence, the memebers had a total of 4 chicken dishes and 8 beef dishes
