Answer:
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Step-by-step explanation:
Given:
Hypotenuse BD = 12 unit
Angle θ = 30°
Find:
Perimeter of rectangle ABCD
Computation:
Using trigonometry function
Sin θ = Perpendicular / Hypotenuse
Sin 30 = CD / BD
0.5 = CD / 12
Length of CD = 6 unit
Cos θ = Base / Hypotenuse
Sin 30 = BC / BD
0.866 = BC / 12
Length of BC = 10.4 unit
Perimeter of rectangle ABCD = 2[Length + Width]
Perimeter of rectangle ABCD = 2[6 + 10.4]
Perimeter of rectangle ABCD = 2[16.4]
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Answer: 1. B 10(15 12 + 8) = 350
2. C
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
The easiest way to solve this is just to put it in your calculator.
But if you want to go deeper, then ln(x)^4 = 4*ln(x)
Since x in this case = e then ln (e)^1 = 1.
ln(e)^4 = 4*ln(e) = 4
If it is a fraction equal to .50 or more you raise it up. if it is lower than .50 you round down'
