Im not so sure about this. I need help making a proof that is 9 steps long. (See image)

Leona [35]

Step-by-step explanation:

Not entirely sure, but I believe something like this:

∠1 + ∠2 = 180° since they are a linear pair;

Since ∠1 = ∠2, we can say:

∠1 + ∠1 = 180°

2(∠1) = 180°

∠1 = 90°

And since:

∠1 = ∠2

∠2 = 90°

So the angle between t and s is 90°;

An angle of 90° means t and s are perpendicular (⊥)

Answer: -1, 14, 62, 98

<u>Step-by-step explanation:</u>

Plug each x-value into the equation and solve for y

$\begin{array}{c|l||c}\underline{\quad x\quad}&\underline{x^2-2}&\underline{=\ y}\\1&1^2-2&=-1\\4&4^2-2&=14\\8&8^2-2&=62\\10&10^2-2&=98\end{array}$
