We can use SOH, CAH and TOA, but first we must find the length of a hypotenuse:
h =
sin (theta)=
2/√13cos ( theta) =
-3/√13tan (theta) =
-2/3cot (theta ) =
-3/2sec (theta) = 1/cos(theta ) =
-√13/3csc(theta ) = 1/ sin (theta) =
√13/2
Answer:
x = 5
Step-by-step explanation:
x + 14 = 19
x + 14 - 14 = 19 - 14
x = 5
Multiplying the numerator and the denominator of a fraction by the same nonzero whole number will change that fraction into an equivalent fraction, but it will not change its value.
Answer: 
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
Based on the information given in the exercise, you can draw the fish tank attached, where the dimensions are: 18 inches high (
), 14 inches deep (
), and 30 inches long (
).
The area that was convered will be the sum of the areas of all the faces, but the top of the tank.
Therefore, the area that was convered is the following:
Two sides are always equal.
