Question

Help due now pleaseee

Answer 1

option - d

Explanation:

a^2 + b^2 = c^2

9^2 + b^2 = 13^2

81 +b^2 = 169

b^2 = 169 - 81 = 88

b=
`√(88)` =
`√(2 x 2 x2 x 11)` ( take the one doubling out )

`\sqrt[2]{2 x 11 }` =
`\sqrt[2]{22}`

Answer 2

d

Explanation:

base² + Altitude² = Hypotenuse²

x² + 9² = 13²

x² + 81 = 169

x² = 169 - 81

x² = 88

x =
`√(88)`

`x = √(2*2*2*11)=2√(2*11)\\\\x=2√(22)`
