Answer:
tan 5π/24.
Step-by-step explanation:
We use the identity:
tan (A - B) = (tan A - tan B) / (1 + tan A tan B)
so the first expression simplifies to
tan ( π/3 - π/8)
= tan 5π/24.
Answer:
20 in³
Step-by-step explanation:
Area of a triangle is half the base times the perpendicular height:
A=0.5bh
=0.5*10*4
=20
(6.75/ 100) X 4.95 = .334
For one magazine the sales tax is $0.334.
Since, both magazine are of same prize. The total she paid for both magazine will be 4.95 + 0.334 + 4.95 + 0.334 = $ 10.57.
Answer = $213.72


Net pay = $213.72 (Rounded off to 2 decimal points)
