A.  The angle formed with the ground would be calculated using sin x = 20/24.
sin^-1(20/24) = 56 degrees.
b.  The angle formed with the house would be calculated using cos y = 20/24.
cos^-1 (20/24) = 34 degrees.
c. The distance the ladder was placed from the house can be calculated using Pythagorean Theorem or Cos 56 = b/24.
24cos56 = b.  b = 13

Answer:

A. 56.40°

B. 33.59°

C. 13.25 feet

Step-by-step explanation:

In the given triangle ABC, AB is the height of window at second floor,

AC is ladder and BC is the ground.

A. In this part we have to measure angle C.

Since Sin c = \frac{AB}{AC}

         Sin c = \frac{20}{24} = \frac{5}{6} = (0.833)

          c =  (56.40)°

B. In this part of the question we have to find angle A.

Since Cos A = \frac{20}{24}=\frac{5}{6} = (0.833)

             A = 33.59°

C. In this part we have to find distance BC.

Since  Tan c = \frac{AB}{BC}

          Tan (56.40) = \frac{20}{BC}

           BC = \frac{20}{(1.51)}= 13.25 feet.

What is the perimeter of a parallelogram, if it's area is 36 cm^2 and the distances between the point of intersection of the dia
IgorC [24]

Answer:

The perimeter of a parallelogram is 30cm.

Step-by-step explanation:

From the question , the given area of a parallelogram is 36 cm².

But the area of a parallelogram can be calculated using below formula

Area = base * height

From the question the distances that exist between the point of intersection of the diagonals and the sides are 2cm and 3cm respectively

There is the same distance between point of intersection of the diagonals and the opposite sides then,

The base of the side with 4cm can be calculated as

ha= 2+ 2= 4cm

But area can be calculated as A= base × height

36= b1 × h1

36=b1 × 4

b1= 9cm

The base of the other side can be calculated with 6cm height

h2= 3+3=6cm

A= b2× h2

36= b2 ×h2

36= b2× 6

b2= 6cm

Then the perimeter of the parallelogram can be calculated as

P= 2(b1 + b2)

= 2(6+9)

= 30cm

Hence,the perimeter of the parallelogram is 30cm

Calculate the midpoint of the line segments joining the two points (-8, -7) and (4,9)
dmitriy555 [2]

Answer:

Step-by-step explanation:

To calculate the midpoint, you need to plug in the values of x and y into the midpoint formula.

M ( x1 + x2/2 , y1 + y2/2)

M [ -8 + 4/2 , -7 + 9/2]

M ( -2, 1)

Can anyone help me with this question ?
TEA [102]

Answer:

addition

Step-by-step explanation:

18 (<u> d </u> - 9 ) = 198

     3

divide both side by 18

<u> d </u> - 9 = <u> 198 </u>  

3             18

<u> d </u> - 9 = 11

3

multiply both sides by 3

d - 27 = 33

add 27 to both sides

d = 33 + 27

lastly, add them together

d = 60

therefore, the last step is addition
