\tan \left(18\right)=\frac{x}{20}
noname [10]

Answer:

x ≈ 6.5

Step-by-step explanation:

We have the epresion tan(18)=\frac{x}{20} and we want to find the value of x.

Let's do it step-by-step

Step 1. Multiply both sides of the equation by 20

tan(18)=\frac{x}{20}

20tan(18)=(\frac{x}{20} )(20)

20tan(18)=x

Step 2. use the reflexive property of equality: if a=b then b=a

20tan(18)=x

x=20tan(18)

Step 3. Using a calculator we get that tan(18)=0.325.  Replacing that value we get

x=20(0.325)

x ≈ 6.5

We can conclude that the value of x is approximately 6.5

The formula for the area of a triangle is a = zon, where b is the length of the base and h is the height.
katen-ka-za [31]

Answer:

The height is 5 units

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh where b is the base and h is the height

30 = 1/2 (12) h

30 = 6h

Divide each side by 6

30/6 = 6h/6

5 = h

The height is 5 units
