AC = √ 25 + 16
AC = √41
AC = 6.40 This is the measure of the hypotenuse.
long leg = 5 distance from -2 to +3 (x - axis)
short leg = 4 distance from 2 to 6 (y - axis)
perimeter = 6.4 + 5 + 4 = 15.4 units

1 point for each match it draws
and 0 points for each match it loses
Jill's team has played 40 matches.
Jill's team has drawn 16 matches.
Jill's team has got a total of 55 points.
How many matches has Jill's team lost?
Answers
Answer:
Jill's team lost 11 matches.
Step-by-step explanation:
Jill's team drawn matches = 16
Points earned for the matches drawn = 16
Total points earned = 55
Therefore, points earned by winning the matches = 55 - 16 = 39
Total matches won by Jill's team =
=
= 13
Total matches won + matches drawn = 16 + 13 = 29
Matches lost by the team = 40 - 29 = 11
Therefore, Jill's team lost 11 matches.
Final answer:
Jill's team has lost 11 matches. This was calculated by subtracting the matches drawn and matches won from the total matches played.
Explanation:
To answer this mathematics question, we first need to know how many points Jill's team has earned from the matches they've drawn. Since each draw earns 1 point and Jill's team has drawn 16 matches, they've earned 16 points from draws. They have a total of 55 points, and if we subtract the 16 from draws, that leaves us 39 points earned from wins. Since a win is worth 3 points, we can calculate the number of matches won by dividing 39 by 3, giving us 13 matches won. As the team has played a total of 40 matches (16 drawn + 13 won), the team has lost the remainder. So, subtract the 29 matches won or drawn from the total 40 to get 11. Therefore, Jill's team has lost 11 matches.

Answer:
5. a,c,b
6. a,b,c
7. v,z,y,w,x
Step-by-step explanation:
5. Given are the measure of sides as 28,17 and 15. The corresponding angles are 'a', 'c' and 'b'.
Using the conjecture: The angle opposite to the greatest side is largest.
Thus for the sides 28,17 and 15. The corresponding angles 'a', 'c' and 'b' are in order from greatest to least.
6. Given are the angles 30, 72 and 75( angles of an isosceles triangle).
Using the conjecture: The angle opposite to the greatest side is largest.
We observe
'a' is corresponding to angle 75°
'b' is corresponding to angle 72° and
'c' is corresponding to angle 36°
Thus a,b,c are the order from greatest to least.
7. Given
'v' is corresponding to angle 122° [180-(30+28)]
'w' is corresponding to angle 42°
'x' is corresponding to angle 34°
'y' is included in three dimensional angle
'z' is included in three dimensional angle
Such that
Thus the order from greatest to least is v,z,y,w,x
