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

A) a²+c²=b²
24² cm 26² cm=c²
-576 cm + 676 cm=c²
100 cm=c²
√100 cm=√c²
10cm=c

B) a²+c²=b²
39² +15²=c²
1521 + 225 =c²
√1746=√c²
41.78 =c
42 = c

4)What is the length of each hypotenuse, to the nearest centimetre? show your work

A) a²+b ²=c²
8² cm + 9² cm=c²
64 cm +81cm=c²
√145cm =√c²
12.0cm=c



B) a²+b²=c²
6² cm +10² cm=c²
36 cm+100 cm=c²
√136cm²=c²
11.6 = c
12 = c

6) Find the height of triangle with a base of 4 cm and a hypotenuse of 11 cm. Round to the nearest tenth of a centimetre. show your work

a²+b²=c²
-4² cm +11² cm=b²
-16 cm +121cm=b²
√105cm=b²
b=10.2
b = 10 cm

  1. Nice post Mussie. I like how you explained your work, but you should try to extend your work a bit more by doing something like this --> (24x24)- (26x26). Also, you could have explained your work for number 8, and try to add a bit of color. Anyways, keep it up!
