A man standing on level ground is 1000 feet away from the base of a 350-foot-tall building. Find,
CaHeK987 [17]

If you sketch the man and the building on paper, you'll have a
right triangle.  The right angle is the point where the wall of
the building meets the ground.  The height of the building
is one leg of the triangle, the line on the ground from the
building to the man's feet is the other leg, and the line
from his feet to the top of the building is the hypotenuse.

We need to find the angle at his feet, between the hypotenuse
and the leg of the triangle.

Well, the side opposite the angle is the height of the building -- 350ft,
and the side adjacent to the angle is the distance from him to the
building -- 1,000 ft.

The tangent of the angle is      (opposite) / (adjacent)

                                                = (350 ft)  /  (1,000 ft) = 0.350 .

To find the angle, use a book, a slide rule, a Curta, or a calculator
to find the angle whose tangent is 0.350 .

           tan⁻¹(0.350)  =  19.29° .  (rounded)

Hi can you help me pleaseeee?)
olganol [36]

<em>So to solve for a variable, you have to isolate that variable onto one side.</em>

<h3>14.</h3>

Firstly, multiply both sides by j: h-4=kj

Next, divide both sides by k and <u>your answer will be: \frac{h-4}{k}=j</u>

<h3>15.</h3>

Firstly, add g on both sides: \frac{x}{5}=a+g

Next, multiply both sides by 5 and <u>your answer will be: x=5(a+g)</u>

<h3>16.</h3>

Firstly, subtract 5p on both sides: 9c=-4p

Next, divide both sides by 9 and <u>your answer will be c=-\frac{4}{9}p</u>

Simplify. (−5 p 4 z 6 u) 3
ser-zykov [4K]
In this expression, solve the multiplication in the parenthesis. 
-5×p×4×z×6×u
since multiplication is commutative, 
-5×p×4×z×6×u=-5×4×6×p×z×u= -120pzu

Now multiply this by 3.
(-5p4z6u)3 = (-120pzu)3 = -360pzu

which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of 1/3 ?
denis23 [38]

Answer:

y-2=\frac{1}{3}(x-3)

Step-by-step explanation:

we know that

The equation of the line into point slope-form is equal to

y-y1=m(x-x1)

in this problem we have

m=\frac{1}{3}

(x1,y1)=(3,2)

substitute the values in the formula

y-2=\frac{1}{3}(x-3)
