The question I chose to do is number 4 from page 110.

You want to find out the height of the pole where the guy wire is attached, to the nearest tenth of a meter.

The triangle isn't labeled as A,B,or C, my mistake.





c²-b²=a²
10²-2²=a²
(10x10)-(2x2)=a²
100-4=a²
96=a²
√96=√a²
9.8=a

Today in class Mr.Harbeck told us to choose any question from 110-113 so I am doing question 6~!

You are asked to check the design plans for a baseball diamond. Is the triangle a right triangle? Explain.

I don't think its a right triangle because on either side of the baseball diamond its still not a right triangle. 

P.S I know that you don't get this but the thing is that without a picture you still wont know so thats why I don't know how to rotate a picture in paint!     D:!

Today Mr. Harbeck said that if we haven't scribe yet we should pick a question. Here is question number 7.

7. What is the height of
the wheelchair ramp?
Give your answer to
the nearest tenth of a centimetre.

c² - b² = a²

80² - 79² = a²

(80x80) - (79-79) = a²

6400 - 6241 = a²

159 = a²

√159 = √a²

12.6cm= a

The wheelchair ramp would be 12.6 cm tall.

Thanks for reading my scribe!

Shahriar knows that the size of a computer monitor is based on the lenght of the diagonal on the screen. He thinks that the diagonal is not as large as the ad says. Is he correct? Explain.

a squared+b squared = c squared

25 square+3o squared = c squared

(25x25)+(30x30) = c squared

625+900=

1525= c squared

He is correct because the right lenght is 39 cm.
