Question

Help with these questions please!

Answer 1

Explanation:

Using Pythagoras Theorem:

`c = \sqrt{{a}^(2) + {b}^(2) }`

7.

`c = \sqrt{ {a}^(2) + {b}^(2) } \\ c = \sqrt{ {24}^(2) + {7}^(2) } \\ c = √(625) \\ c = 25`

8.

`a = \sqrt{ {c}^(2) - {b}^(2) } \\ a = \sqrt{ {13}^(2) - {6}^(2) } \\ a = √(133) \\ a = 11.5`

(cor. to the nearest tenth)

Answer 2

1) c = 25 cm

2) a = 11.532562594 cm
