Question

#1 plz thx!!!!!!!!!!

Answer 1

We have to use pythagorean theorem. The equation is $a^{2} + b^{2} = c^{2}$ so we plug in the numbers (hypothenuse is always C in the equation) $a^{2} + 8^{2} =10^{2}$ now we solve:

$a^{2} +64=100$ Exponents 

$a^{2} =36$ Subtract

a=6 Square Root

x=6 Answer
