Answer and Step-by-step explanation:

90ft = a

55ft = b

50ft = c

Plug into equation.

$50^{2} = 90^{2} + 55^{2} - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4$

29.4° is the answer.

A side of the triangle below has been extended to form an exterior angle of 159º. Find the value of x.

xenn [34]

Answer:

x = 69

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles in a triangle

x+90 = 159

Subtract 90 from each side

x +90-90 = 159-90

x =69
