Question

Find the missing side

Answer 1

7) 8.94

8) 6.71

Explanation:

for both questions, use pythagorean theorem

`a^(2) + b^(2) = c^(2)`

Question 7:

`4^(2) + 8^(2) = c^(2)`

16 + 64 =
`c^(2)`

80 =
`c^(2)`

`√(80) = \sqrt{c^(2)}`

c = 8.94

Question 8:

`6^(2) + 3^(2) = c^(2)`

36 + 9 =
`c^(2)`

45 =
`c^(2)`

`√(45) = \sqrt{c^(2) }`

c = 6.71
