The units in Shante's apartment complex are consecutively numbered on each floor. The sum of her number and her next
hichkok12 [17]

Answer:

222

Step-by-step explanation:

Let x be the number on Shante's doors. The units in Shante's apartment complex are consecutively numbered on each floor, so the number on next door is x+1.

The sum of these numbers is 443, then

x+(x+1)=443\\ \\x+x+1=443\\ \\2x+1=443\\ \\2x=443-1\\ \\2x=442\\ \\x=221\\ \\x+1=221+1=222

The larger of two numbers is 222.

Sav [38]

Answer:

  tan(t) = √(sec(t)² -1)

Step-by-step explanation:

The relation between tangent and secant is ...

  tan(t)² +1 = sec(t)²

Then ...

  tan(t) = ±√(sec(t)² -1)

In the third quadrant the tangent is positive, so ...

  tan(t) = √(sec(t)² -1)
