$a.\\P=2x+2\pi r\\\\b.\\2x+2\pi r=P\ \ \ |-2\pi r\\\\2x=P-2\pi r\ \ \ |:2\\\\x=\dfrac{P}{2}-\pi r\\\\c.\\P=660\ ft,\ r=50\ ft\\\\x=\dfrac{660}{2}-50\pi=(330-50\pi)\ ft\approx330-50\cdot3.14=330-157=173\ ft$

Answer:

Step-by-step explanation:

The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.

Triangle RST:

48 + 73 = 121

180 - 121 = 59

Angle R = 59

Angle T = 48

Angle S = 73

59 + 48 + 73 = 180

Triangle ABC:

73 + 59 = 132

180 - 132 = 48

Angle A = 59

Angle B = 73
