A skate board ramp is built on an incline so that it rests on a porch that is 1.3m high. The bottom of the ramp is placed 2.5m f
mr_godi [17]

Answer:

θ = 27.47°

Step-by-step explanation:

This problem can be represented as a right-angled triangle, as shown in the diagram below.

To find θ, we apply the tangent part of the trigonometric ratios SOHCAHTOA:

tanθ = \frac{opposite}{adjacent}

In the diagram, opposite = 1.3 m and adjacent = 2.5 m

Hence:

tanθ = \frac{1.3}{2.5}

tanθ = 0.52

θ = tan^{-1} 0.52

θ = 27.47°

The ramp forms 27.47° with the ground.

What is the ratio of x to y?<br> 2 x<br> ---- = --------<br> 3 3x+y
Ghella [55]
2/3 = x/(3x + y)

Cross multiply:

3x = 2(3x + y)

Distribute 2:

3x = 6x + 2y

Subtract 6x to both sides:

-3x = 2y

Divide 'y' to both sides:

-3x/y = 2

Divide -3 to both sides:

x/y = -2/3

Which value of x makes the equation 2+4(6-2x)= 8 true?​
Usimov [2.4K]

Answer:

Step-by-step explanation:

2+4(6-2x)=8

2+24-8x=8

26-8x=8

26-8=8x

18/8=x

2.25=x

substitute the value of x

2+4(6-2x)

2+4(6-2*2.25)

2+6

8

therefore 8=8 so it is true
