Answer:
t≅13.33h
Step-by-step explanation:
Adam (A) works at constant rate of 50tiles/h
Briana (B) works at constant rate of 55tiles/h, this means that A=50 tiles per hour and B=55 tiles per hour, then A+B = 105tiles/h together, but the floor consists of 1400tiles, so if 105 tiles are installed in one hour, then 1400 tiles in how long they will be installed?
t = 1400tiles*h/105tiles≅ 13.33 h
Answer:First make sure your calculator is on the right setting which would be a DEG. Then depending on the problem you would press COS, put whats needed inside the parentheses and close it.
Or if a different kind of problem you would press 2nd on the top of the calculator then Cos and continue the same way as the first one.

Answer: 9.85 == 4 = False
Step-by-step explanation: its cant equal the same answer other its odd or even I think whats the answer(I Think that what the question meant....)
Well, 46+42=88 and that divided by 2 is 44. So there ya go.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
1 + tan²A = sec²A , secA = 
, cosecA = 
, cotA = 
, tanA = 
Consider the left side
= 
= 
= 
= 
× sin²A
=
= tanA = right side , thus proven
