Answer:

y = 7/6 * x - 1/6

Step-by-step explanation:

6x + 7y = 126

y = (- 6/7) * x + 18

slope: -6/7

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line

slope' : 7/6

y = mx + b

8 = 7/6 * 7 + b

b = (48-49) / 6 = - 1/6

equation: y = 7/6 * x - 1/6

Answer:

The angle $\theta$ measures approximately $28.81^o$

Step-by-step explanation:

Since this problem involves the finding of an angle in a right angle triangle for which we know the opposite side and the adjacent side, the trigonometric function that relates them is the tangent:

$tan(\theta)=\frac{opposite}{adjacent}$

Then, for our case we get a starting equation that reads:

$tan(\theta)=\frac{opposite}{adjacent} \\tan(\theta)=\frac{7.7}{14}$

and for which we need to solve for $\theta$ . Then we use the arctangent function to get the final answer:

$tan(\theta)=\frac{7.7}{14} \\\theta=arctan(\frac{7.7}{14})\\\theta= 28.81^o$

Mark cast a shadow that is 4 feet long. At the same time, a nearby tree casts a shadow that is 20 feet long. If mark is 6 feet t

Trava [24]

Answer:

30 ft

Step-by-step explanation:

We can use the given information to set up a ratio...

$\frac{Mark's\ height}{Mark's\ shadow}=\frac{Tree's\ height}{Tree's\ shadow}$

$\frac{6\ ft}{4\ ft}=\frac{x}{20\ ft}$

We can solve this ratio using cross multiplication (multiply the numerator of the first fraction by the denominator of the second and the numerator of the second fraction by the denominator of the first):

120 = 4x

Divide both sides by 4

x=30 ft
