Answer:

x=11

Step-by-step explanation:

Due to angles DCA and CAB being Alternate Interior Angles, we know that they will be equal. This means that

$DCA=33$ °

Next, we can find the measure of the angle DCE.

Angles BCE and BCA are supplementary. This means that they will add together to be 180°

This means that 180-BCE=BCA

Which means $BCA=180-5x$

As all of the angles in a triangle must add together to be 180 degrees, we can set up the following equation

$33+180-5x+2x=180\\213-3x=180\\3x=33\\x=11$

Complete the statement using always, sometimes, or never. A rectangle is __________________ a rhombus.

Hi!

A rectangle can sometimes be a rhombus if it has sides of all equal lengths. If a rectangle was a rhombus, it would also be a square. Furthermore, a square is always a rhombus.

Hope this helps! :)

Answer:

${x}^{ - 2} = \frac{1}{ {x}^{2} } \: \: –> {7}^{ - 2} = \frac{1}{ {7}^{2} } = \frac{ 1}{49} \\ \\ {x}^{ - 1} = \frac{1}{ {x}^{1} } \: –> {7}^{ - 1} = \frac{1}{ {7}^{1} } = \frac{1}{7} \\ \\ {x}^{0} –> {7}^{0} = 1 \\ \\ {x}^{1} –> {7}^{1} = 7 \\ \\ {x}^{2} –> {7}^{2} = 49$
