Answer:
b = 35.00
Step-by-step explanation:
To make use of the Law of Sines, you need to know angle B. Of course, its value will make the sum of all angles be 180°, so it is ...
B = 180° -34.5° -29.8° = 115.7°
Then the law of sines tells you ...
b = sin(B)·a/sin(A) = 22·sin(115.7°)/sin(34.5°)
b = 35.00

Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × ( r is the radius )
given arc = 63.48π , then
2πr × = 63.48π ( cancel 2π on numerator/ denominator )
r × π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
