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

Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
