If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.
makvit [3.9K]

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

  • 3x - 31 = 2(x+6)
  • 3x - 31 = 2x + 12
  • 3x - 2x = 12 +31
  • x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98

Determine if the segment lengths form a triangle. If so, would the triangle be acute, right, or obtuse? 4.1, 8.2, 12.2
goldfiish [28.3K]
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.

 4.1 + 8.2 \ \textgreater \  12.2 \\
12.3 \ \textgreater \  12.2 \\
true
They can form a triangle.

Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if c^2=a^2+b^2, the triangle is right
- if c^2\ \textless \ a^2+b^2, the triangle is acute
- if c^2\ \textgreater \ a^2+b^2, the triangle is obtuse

4.1^2+8.2^2=16.81+67.24=84.05 \\
12.2^2=148.84 \\ \\
148.84\ \textgreater \ 84.05
The triangle is obtuse.

The answer is D.
