As you are walking down a path, you see a sign telling the path has a 2% grade (ie., a rise of 2 metres for a horizontal change

Leni [432]

Answer:

Option (A)

Step-by-step explanation:

It has been given in this question that sign telling path has a 2% grade.

2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).

All the trigonometric ratios for the angle θ between the path and the horizontal are,

Sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

Cosθ = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

tanθ = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Since measures of the opposite side and adjacent sides are given

Therefore, tangent ratio will be applied to get the measure of the angle,

tanθ = $\frac{2}{100}$

θ = $\text{tan}^{-1}(\frac{2}{100})$

Option (A) will be the answer.

Simplify expressions <br> 2=3/4x-7

Gnesinka [82]

Answer: x = 12

Step-by-step explanation:

$2=\frac{3}{4}x-7$

Add 7 on both sides to get rid of the 7 and isolate x.

$+7+2=\frac{3}{4}x-7+7$

$9=\frac{3}{4}x$

Now multiply both sides by $\frac{4}{3}$ to eliminate it and isolate x.

$(\frac{4}{3})(9)=(\frac{3}{4}x) (\frac{4}{3})$

$12=x$

Proof;

$2=\frac{3}{4}x-7\\2=\frac{3}{4}(12)-7\\2=9-7\\2=2$
