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
Answer: Im Not really sure but the answer is 303.66
Step-by-step explanation: A=a+b
2h=19+29.2
2·12.6=303.66
