Answer:
365.9 Inches
Step-by-step explanation:
To find the value of Sin A can be found using the sine rule. the rule states that the ratio of the length facing an angle in a triangle to the sine of the angle is constant. As such,
a/Sin A = b/Sin B = c/Sin C
Where is a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.
Hence,
58/Sin 19 = r/Sin 115
r = 58 Sin 115/ Sin 19
= 365.9 Inches
