DOUBLE JEOPARDY! Find the arc length and area of a sector with a radius of 8" and a central angle of 115 degrees?

What is length of 16.1" What is area of 64.2 inches squared

Solve for side length*

Given triangle ABC, A = 47 degrees, C = 32 degrees, c = 12 miles. What is the length of side b?

What is side length b = 22.2 miles

200

Given triangle ABC C = 101 degrees, a = 23 mm, b = 19 mm, Find side length c

What is 32.5 mm

Solve for angle measure*

100

Given triangle ABC, a = 24 km, b = 30 km, c = 21km, Find the measure of angle A

What is 52.6 degrees?

200

Given triangle ABC, B = 77 degrees, b = 50 m, a = 22 m Find the measure of angle A

What is 25 degrees? (180 - 25) = 155 will not work because (155 + 77) degrees = 232 degrees. 232 degrees is more than 180 degrees. 180 degrees is the maximum number of degrees in a triangle
