Textbook Questions

3) Determine the length of each hypotenuse.




A) 20 cm

12 cm = 144 cm²
16 cm = 256 cm²
144 cm² + 256 cm² = 400 cm²
Square of 400 cm² = 20 cm

B) 34 cm

16 m = 256 m²
30 m = 900 m²
256 m² + 900 m² = 1156 m²
Square of 1156 m² = 34 m


4) What is the length of each hypotenuse? Give your answer to the nearest tenth of a centimeter.



A) 9.2 cm

7 cm = 49 cm
²
6 cm = 36 cm²
49 cm² + 36 cm² = 85 cm²
Square of 85 cm² = 9.2 cm

B) 13.6 cm

11 cm = 121 cm²
8 cm = 64 cm²
121 cm² + 64 cm² = 185 cm²
Square of 185 cm² = 13.6 cm

Good job Brayden! I liked how you used different colors and used the picture on the textbook. You explained everything very well which made it easy to understand.

Good job Brayden!! Your scribe was good and it had lots of details on it. I like how you used different kinds of colors so your blog would stand out. Now I know how to find the hypotenuse.

Good Job Again!!!!

Good job Brayden! Good use of colours, represents Sargent Park! But the problem is, yellow is a little hard to see when you are reading it. You also need the formula like a² + b² = c². Other than that, good job and keep up the good work my friend.
