Find the value of x number on top is 6 and other is 9
faltersainse [42]

Answer:

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

x(x + 9) =  {6}^{2}  \\  \\  {x}^{2}  + 9x = 36 \\  \\  {x}^{2}  + 9x - 36 = 0 \\  \\  {x}^{2}  + 12x - 3x - 36 = 0 \\  \\ x(x + 12) - 3(x + 12) = 0 \\  \\ (x + 12)(x - 3) = 0 \\  \\ x + 12 = 0, \:  \: x - 3 = 0 \\  \\ x =  - 12, \:  \: x = 3 \\  \\

A rectangular field has dimension of 91 feet by 60 and 1/3 feet what is the area of the field
Oliga [24]

Answer:

Area = 91*\frac{181}{3}=5490\frac{1}{3} square feet

Step-by-step explanation:

The area of a rectangle is given by the formula:

A = length * width

Where length is 91 feet and width is 60\frac{1}{3}  feet

Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:

a\frac{b}{c}=\frac{(a*c)+b}{c}

Hence,

60\frac{1}{3}=\frac{181}{3}

So, the area is:

Area = 91*\frac{181}{3}=5490\frac{1}{3} square feet

The mnemonic SOH CAH TOA is intended to help you remember the relationship between trig functions and side of a right triangle. In particular, when the adjacent side and hypotenuse are involved, the desired relation is ...

  Cos = Adjacent/Hypotenuse

  cos(35°) = y/15

  y = 15·cos(35°)

  y ≈ 12.3
