Answer:

50 units²

Step-by-step explanation:

The area of a trapezoid can be found using the following formula.

$A=\frac{1}{2}h(b_{1} +b_{2} )$

The height of the trapezoid is 5 units. The bases are 8 units and 12 units.

$h= 5 \\b_{1} = 8\\b_{2} = 12$

Substitute the values into the formula.

$A=\frac{1}{2}*5(8+12)$

Solve inside the parentheses. Add 8 and 12.

8+12=20

$A=\frac{1}{2}*5(20)$

Multiply 5 and 20.

5*20= 100

$A=\frac{1}{2}*100$

Multiply 1/2 and 100 or divide 100 by 2.

100 * 1/2= 50 or 100/2= 50

$A= 50$

Add appropriate units. For this problem, the units are units².

$A= 50 units^2$

The area of the trapezoid is 50 square units.

Answer:

50 square units

Step-by-step explanation:

Using the formula provided, $a = \frac{1}{2}h(b_1+b_2)$ , substituting the height (5), b1 (8) and b2 (12), we can solve for the formula.

$a = \frac{1}{2}\cdot5(8+12)\\\\a = \frac{1}{2}\cdot5(20)\\\\a = \frac{1}{2}100\\\\a = 50$

Hope this helped!

Tan(x+pi) + 2sin(x+pi)=0<br><br>can you help prove this and make the left side equal the right?

vladimir1956 [14]

This is not an identity but an equation. You're supposed to find the values of $x$ for which this is true. It is *not* true for all values of $x$ .

To see why:

$\tan x$ has period $\pi$ , which means $\tan(x+\pi)=\tan x$ .

The angle sum identity for $\sin x$ says that

$\sin(x+\pi)=\sin x\cos \pi+\cos x\sin\pi=-\sin x$

$\tan(x+\pi)+2\sin(x+\pi)=\tan x-2\sin x$

By definition of $\tan x$ ,

$\tan x=\dfrac{\sin x}{\cos x}$

and so

$\tan x-2\sin x=\sin x\left(\dfrac1{\cos x}-2\right)$

which is only 0 if either $\sin x=0$ (which only happens for certain values of $x$ ) or $\dfrac1{\cos x}-2=0\implies\cos x=\dfrac12$ (which also only happens for certain values of $x$ ). It's these values of $x$ you want to find.

$\sin x=0$ whenever $x$ is a multiple of $\pi$ , i.e. $x=n\pi$ for any integer $n$ .

If $0\le x$ , then $\cos x=\dfrac12$ is true for $x=\dfrac\pi3$ and $x=\dfrac{5\pi}3$ . Then to account for all other possible values, we add a multiple of $2\pi$ , so that $x=\dfrac\pi3+2n\pi$ or $x=\dfrac{5\pi}3+2n\pi$ for integers $n$ .
