a)

c² + d² = e²

c² + 24² = 26²

c² + 576 =676

c² + 576 - 576 = 676 - 576

c² = 100

c = √100

c = 10m

b)

b² + a² = c²

b² + 15² = 39²

b² + 225 = 1521

b² + 225 - 225 = 1521 - 225

b² = 1296

b = √1296

b = 36cm

c² + 24² = 26²

c² + 576 =676

c² + 576 - 576 = 676 - 576

c² = 100

c = √100

c = 10m

b)

b² + a² = c²

b² + 15² = 39²

b² + 225 = 1521

b² + 225 - 225 = 1521 - 225

b² = 1296

b = √1296

b = 36cm

a)

c² = a² + b²

c² = 8² + 9²

c² = 64 + 81

c = √145

c = 12cm (nearest centimeter)

b)

c² = a² + b²

c² = 6² + 10²

c² = 36 + 100

c = √136

c = 12cm

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

a² + b² = c²

a² + 4² = 11²

a² + 16 = 121

a² + 16 -16 = 121 - 16

a² = 105

a² = √105

a = 10.2cm

8. Ellie and Lucas are going the skateboard park to try out the new ramp. Is the new ramp a right triangle? Explain your thinking.

a² + b² = c²

2² + 3² = 5²

4 + 9 = 13

13 ≠ 15 (5²)

No, it is not a right triangle because it doesn't equal the hypotenuse/5².

Great job!I like the color,pictures,and how it was well organized.Awesome job,bravo!Keep up the good work!

ReplyDeleteGreat Job Karen, Your post is understandable and neat. The other thing I liked is that you have colors and pictures.
