The triangle has a total of 180 degrees in it , 180-90 = 90 . 90- 60 is 30

so its 30 degrees.

All triangles equal 180 so the answer would be set up as follows:
180-60-90 (right triangle) = 30 degrees
30 degrees is the answer

Y=6x/5 +27 find y-intercept and slope
mixas84 [53]

Answer:

  1. General equation of a line is given by y = mx +c, where m is the gradient /slope, c is the intercept. To find for the intercept on y- axis, put x = 0.
  2. y =  \frac{6(0)}{5 }  + 27 \\ y =  \frac{0}{5}  + 27 \\ y = 27 \\ therefore \: the \: intercept \: on \: y \: is \: 27 \\
  3. By comparison,
  4. y =  mx +  \: c \\ y =  \frac{6}{5} x  \:  +27 \\ m =  \frac{6}{5 \: }  \: \\  hence \: slope \: is \:  \frac{6}{5}

PLEASE HELP ASAP <br> TRIGONOMETRY
otez555 [7]

Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

   cos(x) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

   cos(x) = \frac{27}{30}

   x = \text{cos}^{-1}(\frac{9}{10} )

   x = 25.84

   x ≈ 25.8°

12). By applying tangent rule in the given triangle,

    tan(x) = \frac{\text{Opposite side}}{\text{Adjacent side}}

    tan(x) = \frac{43}{18}

    x = \text{tan}^{-1}(\frac{43}{18} )

    x = 67.29°

    x ≈ 67.3°
