Urgent with circles and triangles needed asap

This problem uses your geometry knowledge of arcs and inscribed angles

The theorem for inscribed angles is: The measure of an inscribed angle is equal to half the measure of its intercepted arc

Therefore, m∠STR= 1/2(Arc SR)

109/2=

54.5

Hope this helped :)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
