Sec 2 A = 1 / cos 2 A
1 / cos 2 A = 1 / sin 13 A
cos 2 A = sin 13 A
2 A = 90° - 13 A
2 A + 13 A = 90°
15 A = 90°
A = 90° : 15

Which number(s) below belong to the solution set of the inequality Check all that apply. x + 30 &lt; 60 a.50 b.45 c.300 d.1 e.29
Igoryamba

Answer:

e.29 d.1

Step-by-step explanation:

  • x+30<60 :

we will replace with the values we have :

  • 300 that's a big number . Obviously it isn't a solution
  • 50 : 30+50 = 80>60 so no
  • 45: 30+45= 75 >60  so no
  • 30+30 = 60 we have < not ≤ so no
  • 1 yes . it's obvious
  • 29 +30 = 59<60 so yes !

Does a two-digit number exist such that the digits sum to 9 and when the digits are reversed the resulting number is 9 greater t
Alexeev081 [22]

The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

I hope this helps!
