Question

ayudaaa porfavorrrrrr​

Answer 1

hipotenusa²=cateto²+cateto²

$1) {z}^{2} = {10}^{2} + {7}^{2} \\ {z}^{2} = 100 + 49 \\ {z}^{2} = 149 \\ z = + \sqrt{149} \\ z = 12.2cm$

$2) {11}^{2} = {x}^{2} + {9}^{2} \\ 121 = {x}^{2} + 81 \\ 121 - 81 = {x}^{2} \\ 40 = {x}^{2} \\ + \sqrt{40} = x \\ 6.32 cm= x$

$3) {10}^{2} = {y}^{2} + {y}^{2} \\ 100 = 2 {y}^{2} \\ 100 \div 2 = {y}^{2} \\ 50 = {y}^{2} \\ + \sqrt{50} = y \\ 7.07cm = y$
