Hi there!

We can use right-triangle trigonometry to solve.

We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.

cosθ = Adjacent/Hypotenuse

We can plug in what is given:

cos(28) = A/17

Solve for 'A':

17cos(28) = <u>15.01 ft</u>

If AC = x + 5 and AB = 3x - 1... what is the length of BC?
Hatshy [7]
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10     |subtract 2 from both sides
3x = 5x - 12      |subtract 5x from both sides
-2x = -12      |divide both sides by (-2)
x = 6

If G(s) is the inverse of S(g) , and G(2) =16 then s(16) = 2 true or false?
lina2011 [118]
If f(x) is the inverse of g(x) then if f(a)=b then g(b)=a

so if G(s) is the inverse of S(g) then if G(2)=16 then S(16)=2, true

yes, it's true

What is the greatest common factor of 48, 24, and 45?
pshichka [43]

Answer:

3

Step-by-step explanation:

Let's write the factors:

48's factors are = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48.

24's factors are = 1, 2, 3, 4, 6, 8, 12, 24.

45's factors are =1, 3, 5, 9, 15 and 45.

The greatest number that is in all three of these lists of factors is 3!

So, 3 is the greatest common factor between all three numbers!
