Answer 1

Answer:

value of x =

$\sqrt{216}$

Step-by-step explanation:

here's the solution,

the given triangle is a right angled triangle so, by applying pythagoras theorem,

=》

$perpendicular {}^{2} = hypotenuse {}^{2} - base {}^{2}$

=》

${x}^{2} = {21}^{2} - {15}^{2}$

=》

${x}^{2} = 441 - 225$

=》

${x}^{2} = 216$

=》

$x = \sqrt{216}$

Answer 2

Okay so basically you put e for the exponents so 21 exponent 2 and 15 exponent and for the x put an exponent of 2 too. So 21*21= 441 and 15*15= 225 then you add 441+225= 666. I believe I am right
