For b) you already have two possibilities, since you have the intercepts.
<span>(20358, 0) and (0,15834) are two possible points, although not very likely. </span>
<span>Solve for y: y= (-7/9)x + 15834 </span>
<span>Any multiple of 9 will give whole number answers. </span>
<span>Let x= 9 </span>
<span>Then y= (-7/9)(9)+ 15834 </span>
<span>Y= 15827 </span>
<span>If you want more reasonable answers, let x= 9000 </span>
<span>Then y= (-7/9)(9000)+ 15834 </span>
<span>Y= 8834 </span>
The sum of the 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48 = 42 degrees.
See attached picture:
Blue: 6/20 or 1/5
Red: 3/20
Yellow: 2/20 or 1/10
Hope this helps
