Answer:

\frac{\pi}{4}

Step-by-step explanation:

\sf let \: y =  { \tan }^{ - 1} ( \tan  \frac{3\pi}{4} ) \\  \\  \sf  \hookrightarrow  \tan y =  \tan  \frac{3\pi}{4}  \\  \\  \sf \hookrightarrow  \tan y =  \tan(\pi -  \frac{\pi}{4} )  \\  \\  \sf \hookrightarrow  \tan y =  \tan( -  \frac{\pi}{4} )  \\  \\  \sf  \hookrightarrow  \tan y =  -  \tan  \frac{\pi}{4}  \\  \\  \boxed  {\hookrightarrow{ \bold{y =  -  \frac{\pi}{4} } } }

Find the missing length.
grin007 [14]

Answer:

  D.  25

Step-by-step explanation:

The left end of the baseline has measure (x-16). In this geometry all of the right triangles are similar, so the short-to-long side ratios are proportional:

  (x -16)/12 = 12/16

  x -16 = 9 . . . . . . . multiply by 12

  x = 25 . . . . . . . . . add 16

The unknown length x is 25.

Please, I need help I'm way behind.
gregori [183]

Answer:

\frac{18√2}{√3}

Step-by-step explanation:

  1. The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
  2. The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
  3. We can get the length of the longest side of the bottom triangle is 9×2÷√3 = \frac{18}{√3}
  4. And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is \frac{18}{√3}x√2
