The trigonometric function gives the ratio of different sides of a right-angle triangle. The area of the triangle is 55.4256 ft².

<h3>What are Trigonometric functions?</h3>

The trigonometric function gives the ratio of different sides of a right-angle triangle.

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

For the given triangle the length of AB and BC can be written as,

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Sin(30^o) = \dfrac{AB}{AC}\\\\\\AB = Sin(30^o) \times 16 \\\\\\AB=8\rm\ ft

Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Cos(30^o) = \dfrac{BC}{AC}\\\\\\BC = Cos(30^o) \times AC\\\\\\BC = 13.8564\rm\ ft

Now, the area of the triangle is,

Area of triangle = 0.5× 8 × 13.8564 = 55.4256 ft²

Hence, the area of the triangle is 55.4256 ft².

What is the solution of the system?
IgorC [24]
What you must do for this case is to solve the system of two equations with two unknowns.
 To find the values of x and y.
 We have then:
 -3x + 9y = 36
 4x + 12y = 24
 Resolving:
 Step 1: 
 (1/3) * (- 3x + 9y) = (36) * (1/3)
 (1/4) * (4x + 12y) = 24 * (1/4)
 -x + 3y = 12
 x + 3y = 6
 Step 2:
 6y = 18
 y = 18/6
 y = 3
 Step 3:
 -x + 3y = 12
 -12 + 3y = x
 -12 + 3 (3) = x
 x = -3
 answer:
 x = -3
 y = 3

Multiply. Express your answer in simplest form 3 3/4 x 2 2/9
blagie [28]

Answer:

25/3

Step-by-step explanation:

To solve this kind of question we will have to convert them to an improper fraction

3 3/4×2 2/9

So the improper fraction will be

15/4×20/9

We discovered that 3 divide both 15 and 9 to give

5/4×20/3

4 also divide both 4 and 20 to give

5/1×5/3

Which will also give

25/3

Therefore the final answer is 25/3
