Answer:

x =31

Step-by-step explanation:

If you see that's a straight line, and the straight line is always 180 degrees, there fore if you use this 56+4x=180 the x will be 31.

Answer:

x = 31

Step-by-step explanation:

angles formed on a straight line have a sum of 180°

Thus, 4x + 56 = 180

4x + 56 = 180

* subtract 56 from each side *

56 - 56 cancels out

180 - 56 = 124

4x = 124

* divide both sides by 4 *

4x / 4 = x

124 / 4 = 31

we're left with x = 31

Answer:

21.74 ft

Step-by-step explanation:

We use Cosine because we are dealing with the Adj and Hyp

Cos 85 = x/20

x = 20 Cos 85

x = 1.74 feet away from the base of the wall.

Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft

What is the equation of the line AB, if it passes through (-4,0), and is parallel to the line

Karo-lina-s [1.5K]

Rewriting the equation of the given line in slope-intercept form,

$-x-4y=1\\\\-4y=x+1\\\\4y=-x-1\\\\y=-\frac{1}{4}x-\frac{1}{4}$

From this, we know the slope of the given line is -1/4.

Since parallel lines have the same slope, we know the line whose equation we want to find has a slope of -1/4.

Substituting into point-slope form,

$y=-\frac{1}{4}(x+4)\\\\\boxed{y=-\frac{1}{4}x-1}$
