17 is a prime number because it’s only divisible by 1 and it’s self, so it only has 2 factors.
Let AB extended intersect DC extended at point E
<span>We now have right triangle BEC with E = 90 degrees </span>
<span>For triangle BEC: </span>
<span>Exterior angle at E = 90 </span>
<span>Exterior angle at C = 148 (given) </span>
<span>Exterior angle of all polygons add up to 360 degrees </span>
<span>Exterior angle at B = 360−148−90 = 122 </span>
<span>So in quadrilateral ABCD </span>
<span>B = 122 </span>
<span>D = 360−44−148−122 = 46</span>

7 is <span>tens of thousands.</span>
Sure. So the hundreds digit is after the tens digit which is 3, so therefore it's 4. The millions digit is 7 places to the left, so it's 7. Ten thousands digits are 5 places to the left, so it's 9. The hundred thousands is 6 to the left, therefore 8. Finally, the thousands is 4 places to the left, so it's 0. Hope this helped!
