Answer:
line NM
Step-by-step explanation:
Since planes extend infinitely in all directions, planes intersect at a line, not at a line segment.
Since this is a right triangle, we could use the pythagorean theorem: a²+b²=c² where this problem already gave us a=10 and b=√60, and we want to solve for c.
10²+(√60)²=c² ← 10² is 100, and the square cancels out the square root on the 60
100 + 60 = c²
160 = c² ← To isolate c, we take the square root of both sides
√160 = c ← √160 is the same as 4√10
Answer: 4√10
It would be 69 inches long m8
It should be Acute Scalene
