Answer:
13
Step-by-step explanation:
8/2=16/4
=4
x-3=2.5*4
x=10+3
x=13
It's angles 9 and 10.
Supplementary angles are two angles that add up to 180°.
So, supplementary angles both "stick" off of a straight line. (Because a straight line is 180°).
This item has no choices given,but here's how to check this out.
<span>Take the three sides of a triangle, add them in pairs. Check if the sum is greater than (not equal to) the third side.</span>
If that is true, then it is possible to construct a triangle with the given side lengths.
Let us try the measure of line segments given above.
3 + 5 > 3 3 + 3 > 3 5 + 3 > 3
8 > 3 6 > 3 8 > 3
You see, each side lengths are greater than the third side length, therefore, you can construct a triangle out of these segment lengths.
