Answer:
Q6. 28.91 Q9. 23.685
Step-by-step explanation:
if you are trying to find the missing side lengths you need to use the Pythagorean theorem which is a squared plus b squared equals c squared, a^2 + b^2 = c^2 but you can only use the Pythagorean theorem on right triangles I assume that they are right because you have little squares in the corners
QUESTION 6
- 30^2 = 8^2 + b^2
- 900 = 64 + x^2
- subtract 64 from both sides
- 836 = b^2
- take the square root of both sides
- 28.91 = b
QUESTION 9
- 25^2 = 8^2 + b^2
- 625 = 64 + b^2
- subtract 64 from both sides
- 561 = b^2
- take the square root of both sides
- 23.685 = b
