**Homework Book Pages 30 questions 2, 3, 4**

**2)**Use the relationship to determine the length of C in each triangle, to the the nearest whole number. Show your work.

A)

b2=c2 - a2

b2=262 - 242

b2=676 - 576

b2=100m2

square root 100 m2 and it becomes 10m

B)

a2=c2 - b2

a2=392 - 152

a2=1521 - 225

a2=1296 cm2

square root 1296 cm2 and it becomes 36cm

**3)**Determine the length of each hypotenuse. Show your work.

A)

a2 + b2 = c2

402 + 92 = c2

1600 + 81 = c2

1681 cm2 = c2

square root 1681 cm2 and it becomes 41cm

B)

a2 + b2 = c2

352 + 122 = c2

1225 + 144

1369m2 = c2

square root 1369 m2 and it becomes 37m

**4) What is the length of each hypotenuse, to the nearest centimeter? Show your work.**

**A)**

a2 + b2 = c2

82 + 92 = c2

64 + 81 = c2

145 = c2

square root 145 cm2 and it becomes 12.04cm

B)

a2 + b2 = c2

102 + 62 = c2

100 + 36 = c2

136 cm2 = c2

square root 136 cm2 and it becomes 11.66 cm

Good Job Louis. I like your post, its organize. I suggest that next time try to highlight important words. Adding a video and a link will help us more. Other than that, good job.

ReplyDeleteGood job Louis! Your post was simple and easy to read. I liked that you showed your work but next time you should add some colour to the important words. You should also add a link and video.Otherwise great job.

ReplyDeleteGood job Louis. I like the way you explained your work, it was very easy to understand. I like how you changed the color for the answer of the hypotenuse. I think you shouldn't space things out as much. You should try and find a video and a link, but overall great job!

ReplyDeleteGreat job Louis. I like how you explained how you found the answers. Its also very neat and easy to read. I agree with anna, you should of highlighted the important words. but fantastic job, keep it up!
