Because it is x² = 4 this means to get a singular x you'd square root it (√4)

and the answer will equal = 2

10 x 10 (also can be written as 10 squared)

10 (squared) shows with a small two (2) being the square sign and this means for 10 x 10 there are 2 lots of 00's

so it makes 1_ _ (100)

How do you know aliens even have milk?

you'd do 6960 x 1.03 (103%) to get answer

but i found the answer for you :)

= 7168.8

toa

tan theta = 0/a

tan 43 = x/9.3

x = 9.3xtan43

x = 8.67

(i think this is pretty much right, but to be sure can someone check?)
