i= √-1

Then i² means we'll square both sides.

i² = (√-1)²

Find the value of x. Round your answer to the nearest tenth. Show your work please!
netineya [11]
To find x we can use that fact that x is in the adjacent side of the 22° angle. We also know that 11 is our hypotenuse. Now, we can use trigonometry to find x.

cos(Ф)=adjacent/hypotenuse
cos(22°)=x/11
11 · cos(22°)= x/11 · 11    multiplicative inverse
11 cos (22°)=x
10.2≈x
