If you add the whole number to the whole number part of the mixed number, and then add the fraction from the mixed number on to the end of that, you get a new mixed number which is your answer.
Answer:
X=140
Step-by-step explanation:
<em>Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees</em>
<em>The attachment you are showing us shows that we already know two angles</em>
<em>(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360. </em>
<em />
X+70+60+90=360
X=360-70-60-90
X=140
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.
