What is an equation of a line, in point-slope form, that passes through (1, −7) and has a slope of −23 ?
DENIUS [597]

The equation a line is:

y - y1 = m(x - x1)

Substitute the slope and the coordinate.

y - (-7) = -23(x - 1)

y + 7 = -23(x - 1)

D) y + 7 = -23(x - 1) is the solution

Kazeer [188]

Answer: 10 ft

Explanation

As two right triangles (a triangle with a 90º angle) are formed, to know the distance between AB we have to calculate BC, AC and subtract.

0. Calculating BC

We have a 30º angle and an adjacent side 5√3ft (as the hypotenuse is the side opposite to the 90º angle). Thus, using the tangent function where:

\tan\theta=\frac{opposite}{adjacent}

we can find the opposite side, which is BC. Replacing the values and simplifying we get:

\tan(30\degree)=\frac{BC}{5\sqrt{3}}BC=5\sqrt{3}\tan(30\degree)BC=5ft

Thus, the segment BC measures 5ft.

<em>2. Calculating segment AC</em>.

In this case, our hypotenuse changes. However, we are still looking for the opposite side. Using the tangent function as before we get:

AC=5\sqrt{3}\tan(60\degree)AC=15

<em>3. Calculating the distance between A and B</em>

AC-BC=15-5=10ft
