Answer:
sinθ = 5/13
cosθ = 12/13
tanθ = 5/12
Step-by-step explanation:
Get the remaining side(hypotenuse) first,
hypotenuse^2 = 12^2 + 5^2 (Pyth. theorem)
hypotenuse = 13
sinθ = 5/13
cosθ = 12/13
tanθ = 5/12
Answer: 11 < x < 35
suppose: the length of the third side is x
because x is the third side of a triangle
=> 23 - 12 < x < 23 + 12
⇔ 11 < x < 35

Answer:
1,440 degrees (10 interior angles of 144 degrees)
Step-by-step explanation:
Answer:
1/12
Step-by-step explanation:
You are close but 1/27 includes people who did not study but still passed. If you want a singular value you should look at the value for the for only the people who studied even if they passed.
Answer:
short story has 32 pgs
novel has 416 pgs
Step-by-step explanation:
a novel (N) has 13 times as many pages as a short story (x) so, N = 13X
total pages is the equation N + x = 448
plug the equation for N into this
13x + x = 448, combine like terms
14x = 448, divide both sides by 14
x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.
