The safety instructions for a 20 foot ladder say the ladder should not be inclined more than 70 degrees with the ground. suppose
Romashka [77]

Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet

Step-by-step explanation:

The scenario is shown in the attached photo.

Right angle triangle ABC is formed when the ladder leans against the wall of the house.

AC = the height of the ladder

AB = x feet = distance of the base of the house to the foot of the ladder

BC is the wall of the building.

To determine x, we will apply trigonometric ratio

Cos # = adjacent/hypotenuse

Where

# = 70 degrees

Hypotenuse = 20

Adjacent = x

Cos 70 = x/20

x = 20cos70

x = 20 × 0.3420

x = 6.84 feets

The length of a rectangle is 6.7 more than 2 times the width. If the perimeter of the rectangle is 57.2 cm, what are its dimensi
Gemiola [76]
From the description, you can get two equation that looks like this:

L= 2*W+6.7cm
Perimeter= 57.2cm

Using perimeter formula, you can put the first and second equation like this:

perimeter= 2L + 2W
57.2cm= 2(2*W+ 6.7)+2W
57.2cm= 4W+ 13.4+ 2W
57.2- 13.4= 6W
W= 43.8/6= 7.3 cm

L= 2W+ 6.7
L= 2*7.3 + 6.7= 21.3
Answer: <span>A. Length=21.3 cm; width=7.3 cm</span>
