Mary is standing out on the balcony of her apartment which is 40 feet above the ground and looks up at a 31° angle to see her fr

Sergio [31]

Answer:

52 feet

Step-by-step explanation:

This situation can be represented by the attached figure as in the answer area.

Let M be the location of Mary.

Let S be the location of Sue.

Distance between apartments is given as 20 feet.

Distance between ground and balcony of Mary is 40 feet.

There is a right angled $\triangle MOS$ .

$\angle OMS = 31^\circ$

To find:

The distance SO + 40 feet.

We can use tangent ratio here in right angled $\triangle MOS$ .

$tan\theta = \dfrac{Perpendicular}{Base}$

$tan31^\circ = \dfrac{SO}{MO}\\\Rightarrow tan31^\circ = \dfrac{SO}{20}\\\Rightarrow SO=20\times 0.6\\\Rightarrow \bold{SO=12\ ft}$

Height of Sue above ground = 40+12 = <em>52 feet</em>

I do suppose that you refer to adding these quantities:
6/1 + 21 = 6 + 21 = 27
<span>and
6/10 + 21
</span>= 3/5 + 21
= 3/5 + 105/5
= 108/5

Give the slope-intercept form of the equation of the line that is perpendicular to –7x – 8y = 12 and contains P(–3, 1)

snow_lady [41]

Answer:

(-7/8)

Step-by-step explanation:

the line is -7x -8y =12

its slope = -(-7/-8)= -7/8

it passes through P(-3, 1)

(y-1)=(-7/8)(x+3)

y-1 = (-7/8)x - 21/8

y = (-7/8)x -13/8
