Answer:

Tan.

Step-by-step explanation:

First way;

Tan (90-θ )=Cot θ Tan (90+θ )= -Cot θ

1st explanation, QUOTATIONS!

"tan90∘ is undefined because you can't divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined."

2nd explanation, QUOTATIONS!

"That's undefined because as you approach 90° from either direction, tan approaches positive or negative infinity. cot(90°) hence approaches 1/infinity (either positive or negative) which is just 0."

A set of stairs is being built as shown.

Step-by-step explanation:

using Pythagoras a²+b²=c²

HOWEVER you know the hypotenuse

so it's rearranged to either c²-b²=a² or c²-a²=b²

so 13²-11²

so 169-121

this makes 48

square root 48 is 6.90 inches
