Answer:
∠ KLJ = 70°
Step-by-step explanation:
The segment KL joins the midpoints of 2 sides of the triangle and is therefore parallel to the third side HG , then
∠ KLJ and ∠ HGL are corresponding angles and are congruent , so
∠ KLJ = 70°
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.

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

, the triangle is right
- if

, the triangle is acute
- if

, the triangle is obtuse

The triangle is obtuse.
The answer is D.

Answer:
328
Step-by-step explanation:
If z is 0, then x has 9 choices. Therefore, z and x can be chosen in (1 × 9) + (4 × 8) = 41 ways. For each of these ways, y can be chosen in 8 ways. Hence, the desired number is 41 × 8 = 328 numbers 3-digit even numbers exist with no repetitions.
5/9 is already in it's simplest form
4/6 can be reduced to 2/3
