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)

What is the slope of the line?
Basile [38]

Answer:

\boxed { \frac{1}{2} }

Step-by-step explanation:

We can find the slope by using rise over run.

Given the coordinate points that are part of the graph.

(1,4) \\ ( - 1,3)

m =  \frac{ 4 - 3}{1 - ( - 1)}  \\ m =  \frac{1}{1 + 1}  \\ m =  \frac{1}{2}

Therefore the slope is 1/2.

Domain = x<18000(You cant og a negative number)
Am I actually supposed to graph it? enter the equation on desmos.com
It takes longer to make the same altitudinal gain
t=50log(18000/(18000-4000))=50log(18000/14000)=5.457
