OK. so for my scribe, I decided to do question 14 on page 113 so here it is.

14).the question for this is find the missing side length of each triangle.

a)c+b=d-each of these letters are supposed to be squared

12m+5m=d-each of these letters are supposed to be squared

(12mx12m)+(5mx5m)=d-the d is supposed to be squared

144+25=d-the d is supposed to be squared

169=d-the d is supposed to be squared

169=d-the d is supposed to be squared and their should be a square root over the 169 and d

13=d

b)w-t=v-each of these letters are supposed to be squared

15cm-9cm=v-each of these letters are supposed to be squared

(15cmx15cm)-(9cmx9cm)=v-the v is supposed to be squared

225-81=v-the v is supposed to be squared

144=v-the v is supposed to be squared

144=v-the v is supposed to be squared and their should be a square root over the 144 and v

12=v

So A's side length is 13m and B's side length is 12cm.
