NEED THE ANSWER ASAP! Find the measure of the missing angle X
jasenka [17]

Answer:

50°

<u>In</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>determine</u><u> </u><u>the</u><u> </u><u>unknown</u><u> </u><u>angle</u><u>,</u><u> </u><u>be</u><u> </u><u>sure</u><u> </u><u>to</u><u> </u><u>use</u><u> </u><u>the</u><u> </u><u>total</u><u> </u><u>sum</u><u> </u><u>of</u><u> </u><u>1</u><u>8</u><u>0</u><u>°</u><u> </u>

120° - 180°= <em><u>60°</u> </em>( this give you the red side inside the triangle)

Then you simple add the two number inside the triangle

<em><u>6</u><u>0</u><u>°</u></em> + 70° = <em><u>130°</u></em>( then you use this to find the missing corner by subtracting from 180°)

180°- <u>1</u><u>3</u><u>0</u><u>°</u> = 50° this is your missing angle X"

To prove it simple add all the 3 angles inside the triangle add up to 180°

<u>6</u><u>0</u><u>°</u> + <u>7</u><u>0</u><u>°</u> + <u>5</u><u>0</u><u>°</u> = <u>1</u><u>8</u><u>0</u><u>°</u>

<u>X</u><u> </u><u>=</u><u> </u><u>5</u><u>0</u><u>°</u>

What does a vector do to a translation
Alona [7]

Answer:

A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. In other words, a translation vector can be thought of as a slide with no rotating. The slide won’t change the shape or size of the figure, and with no rotation, the orientation won’t change either.
