If x² = 196, then we must do the inverse (square root) to find x. However, the square root of any positive number will always be ± (plus or minus).
That means you have to do:
√196 = x
x = <span>±14.
We can check this by doing:
14 </span>× 14 = 196
-14 × -14 = 196
Therefore the answer is B) -14, 14.
The missing angle would be :
90°[right angle] + 45° = 135
180 - 135 = 45°
I took 135 away from 180 because angles in a triangle always add up to 180°
Hi Kimberlys969pdrfzz,

Seventeen and eighty-eight thousandths
we have that
Seventeen ------> 17
eighty-eight thousandths ------->0.088
so
17+0.088=17.088
<h2>answer is 17.088</h2>
