Question

This is my last question and I don’t want to mess up this test this is my final question

Answer 1

Answer:

y = 8.9

Step-by-step explanation:

according to pythagorus theorem,

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

( where p = perpendicular, b = base and

h = hypotenuse )

so,

=》

$y {}^{2} = 12 {}^{2} - 8 {}^{2}$

=》

$y {}^{2} = 144 - 64$

=》

$y {}^{2} = 80$

=》

$y = \sqrt{80}$

=》

$y = 8.9$

i hope it helped....
