Answer:

60

Step-by-step explanation:

What we know:

  • ABD is a straight angle, it measures 180 degrees
  • Angle CBA + CBD = 180 degrees
  • Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9     /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°

Find a numerical value of one trigonometric function of x for cscx=sinxtanx+cosx
ehidna [41]

cscx = sinx tan x + cos x

Using xsx x = 1/sin x and tan x = sin x/cos x

\frac{1}{sin x} = sinx *\frac{sinx }{cos x} + cosx

\frac{1}{sin x} = \frac{sin^2x +cos^2x}{cos x}

\frac{1}{sin x} = \frac{1}{cos x}

Multiplying both sides by cos x

\frac{cos x}{sin x} = 1

cot x =1

Correct option is d .

a cleaning company charges a flat fee of $8 and $30 per hour to clean a home. write an equation that can represent the situation
Andru [333]
In order to reach the total cost of $128, you need to find the number of hours the company cleaned. The equation to do so would be
 
  30x+ 8 = 128

If you subtract 8 from both sides and then divide by 30 you'll find that x=4.
