Question

Please find x for numbers 1 & 2. Greatly appreciated:)

Answer 1

1. 14.5

2. 16

Explanation:

1. a^2 + b^2 =c^2

20^2 + 21^2 = c^2

400 + 441 = c^2

841 = c^2

`√(841)` =
`√(c)`

29 = c

29/2 = x

14.5 =x

2. c^2-b^2 = a^2

34^2 - 30^2 = a^2

1156 - 900 = a^2

256 = a^2

`√( 256 )` =
`√(a)`

16 = a
