ANSWER

9.7 units

Step-by-step explanation

According to the Pythagoras Theorem, the square of the hypotenuse is equal to the sum of the squares of the two shorter legs

${x}^(2) + {7}^(2) = {12}^(2)$

This implies that,

${x}^(2) + 49= 144$

Group similar terms,

${x}^(2) = 144 - 49$

${x}^(2) = 95$

x = √(95)

$x = 9.7 \: units$

to the nearest tenth.
