What is the question though?? and what are the answer choices??
6.4 rounded to the nearest whole number will be 6.
if the decimal was 5 or larger, it would’ve been 7.
Answer:
4,600
Step-by-step explanation:
1,200+1,200+1,100+1,100
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.
