If the triangle is a right triangle, then
(3x)² + x² = (10)² .
9x² + x² = 100
10x² = 100
x² = 10
x = √10 = approx. 3.1622...
If ' x ' is <em>anything less than √10</em> , then the short sides are too short
to make a right angle at the top, and the angle where they meet
is obtuse.
' x ' has to be greater than 2.5 ... otherwise the two short sides
can't stretch far enough to reach both ends of the long side (10) .
So, if 2.5 < x < √10 , then there is a triangle, and it's obtuse.
I set it up as an equation. 1/4x = 1/7x + 3. After you solve it out, it’s 28.
Idk Thai is for me to get points
I think its B
that's THINK i'm not completely sure
Im so sorry but I didn't learn that yet
