Answer 1

Answer:

144

Step-by-step explanation:

20²-16²

pythagorean theorem

a²=b²-c²

Answer 2

aHere's the solution,

According to pythagoras theorem :

=》

$h {}^{2} = p {}^{2} + {b}^{2}$

where,

• h = hypotenuse
• p = perpendicular
• b = base

=》

$20 {}^{2} = 16 {}^{2} + {x}^{2}$

=》

$400 = 256 + {x}^{2}$

=》

${x}^{2} = 400 - 256$

=》

$x {}^{2} = 144$

=》

$x = 12$

hence, value of x = 12
