Answer:
35.2
Step-by-step explanation:
First, convert 25% into decimal form which is= .25
Then, do 8.80 dived by .25 and you get 35.2
20% of 850 was paid in cash..
0.20(850) = 170 was paid in cash
so (850 - 170) = 680 was not paid in cash
Answer:
R = √2
α = π/4 or 45°
Step-by-step explanation:
R cos(2n + α)
Use angle sum formula:
R [cos(2n) cos α − sin(2n) sin α]
R cos(2n) cos α − R sin(2n) sin α
Match the coefficients:
R cos α = 1
R sin α = 1
Divide:
tan α = 1
α = π/4 or 45°
Solve for R:
R cos(π/4) = 1
R / √2 = 1
R = √2
