Answer:

12.9

Step-by-step explanation:

So, we're looking for the side of a triangle.

We are going to use a trig function, tan(x), which is equal to the opposite side of x (the angle) over the adjacent side

In this case, tan (35) = 9/x

we then move the x to the other side by multiplying both sides by x

x * tan(35) = 9

then we divide both sides by tan(35)

x = 9/tan(35)

this answer comes out to (rounded to the nearest tenth) 12.9

Feel free to ask if you have more questions on this response. Hope it helped!

To divide fractions, write the divison as multiplication by the reciprocal of the divisor :

2     -8       2      9

—  ÷  ——   =   —  •  ——

3     9        3     -8

(0--3/4)+1/5

Least Common Multiple:

     20

Left_M = L.C.M / L_Deno = 5

Right_M = L.C.M / R_Deno = 4

Answer:

  17/99

Step-by-step explanation:

Replace the digits 23 in your example with the digits 17 and you have your answer:

  0.\overline{17}=\dfrac{17}{99}

_____

In general, a 2-digit repeat will have 99 as its denominator. If the digits are a multiple of 3 or 11, then the fraction can be reduced. 17 is prime, so the fraction cannot be reduced.
