Two sides of a right triangle are 8 and 12. Find the missing side length if 8 and 12 are legs. ​

Approximately 14.42

Step-by-step explanation:

All you have to do is use the Pythagorean Theorem! In case you don't remember, it's a² + b² = c², where a and b are legs and c is the hypotenuse.

So...

8² + 12² = c²

64 + 144 = c²

208 = c²

= 14.42

14

step-by-step explanation:

14 x 3 = 42

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
