Answer:
Here the answer is 10=a
Step-by-step explanation:
= Tan 2A = cot(A+60°)
= cot(90-2A) = cot (A+60°)
= 90°-2A = A+60°
= 90°-60° =A+2A
= 30 = 3A
= 30\3 = A
= 10 = A

The answer is $54.4. 34 - 40% = 20.4, 20.4 + 34 = $54.4.
Length of arc = Cr where C = angle of rotation and r = radius
31 = C*11
C = 31/11 = 2.8 radians to nearest tenth
