Answer:
the third one where they intersect at 2 and -2
Step-by-step explanation:
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:1) Square all 3 sides.36, 27, 61
</span><span>
<span>
<span>
1,296, </span></span></span>
<span>
<span>
<span>
729, </span></span></span>
<span>
<span>
<span>
3,721
</span>
</span>

<span><span>2) Sum the squares of the 2 shortest sides.1,296 + 729 = 2,025
3) Compare this sum to the square of the 3rd side.2,025 < 3,721
if sum > 3rd side² Acute Triangleif sum = 3rd side² Right Triangleif sum < 3rd side² Obtuse TriangleTherefore, it is an Obtuse TriangleSource:http://www.1728.org/triantest.htm

2300÷100=23
411÷23= 17.87
final answer is 17.87℅
In order to isolate k, we would first cross multiply
3*k=9*10
3k=90
Then to isolate k, we would divide both sides by 3 to get:
K=30
Hope this helps
