**#6 - Determine the length of the leg for each triangle.**

6 a)-

c² - a² = b²

25² - 7² = b²

625 cm² - 49 cm² = b²

576 cm² = b²

√576 cm² = √b²

24 cm = b

6 b)-

t² - s² = r²

26² - 24² = r²

676 cm² - 576 cm² = r²

100 cm² = r²

√100 cm² = r²

10 = r

**#9 -Tina wants to construct a path along the diagonal of her yard. What length will the path be? Express your answer to the nearest tenth of a metre.**

a² + b² = c²

6² + 12² = c²

36 m² + 144 m² = c²

180 m² = c²

√180 m² = √c²

13.4 m = c

The length of the path will be 13.4 m long

**#12-The hypotenuse of the triangle cuts the circle in half. What is the diameter of the circle? Express your answer to the nearest tenth of a centimetre.**

a² + b² = c²

7² + 5² = c²

49 cm² + 25 cm² = c²

74 cm² = c²

√74 cm² = √c²

8.6 cm=c

The diameter of the circle is 8.6 cm

**#15- The coordinate grid shown was drawn on centimetre grid paper. What is the length of line segment AB? Express your answer to the nearest tenth of a centimetre.**

a² + b² = c²

4² +2² = c²

16 cm² +4 cm² = c²

20 cm² = c²

√20 cm² = √c²

4.5 cm = c

The line segment is 4.5 cm.
