Enter the trigonometric equation you would use to solve for x. Do not solve the equation.
pentagon [3]

Answer:

x=12\times \text{tan}(20^0)

Step-by-step explanation:

From the figure attached,

Measure of an angle = 20°

Measure of the opposite side = x

Measure of the adjacent side = 12

By applying tangent rule in the given right triangle,

tan(20°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

\text{tan}(20^0)=\frac{x}{12}

x=12\times \text{tan}(20^0)

Therefore, equation to get the value of 'x' will be,

x=12\times \text{tan}(20^0)

Please help! Does anyone know how to work this surface area question out???
Alik [6]
Surface area of a cylinder=(2xxradiusxheight)+(xradius^2x2)

Radius=Diameter/2
Radius=6/2
=3 m
Height=14 m
Surface area=(2xx3x14)+(x3^2x2)
Surface area=263.8937829+56.54866776
Surface area=320.4424507 m^2
=320.4 m^2

Tin of paint: 90 m^2/3.70 euros
Number of tins needed=320.4/90
=3.56 cans of paint
Price=3.56x3.70
Price=13.172 euros

Hope this helps!
P.S. the “^” sign means “to the power of”

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2)
MrMuchimi

Answer:

y = -2x + 2

General Formulas and Concepts

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, 4)

y-intercept (0, 2)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{2-4}{0+1}
  2. Subtract/Add:               m=\frac{-2}{1}
  3. Divide:                          m=-2

<u>Step 3: Write linear equation</u>

y = -2x + 2
