A surveyor sights the top of a building with a handheld range finder. the top of the building is 148 feet 2 inches away. the ang
Leokris [45]

see the attached figure to better understand the problem


we know that

in the right triangle ABC

cos 56°=AC/AB

where

AC is the adjacent side to angle 56 degrees------> the distance from the surveyor to the building

AB is the hypotenuse-----> 148 ft 2 in

56 degrees------> is the angle of elevation

so

cos 56°=AC/AB---------> solve for AC

AC=AB*cos 56°

AB=148 ft 2 in

convert 2 in to ft

1 ft -----> 12 in

x ft------> 2 in

x=2/12-----> x=0.17 ft

AB=148 ft 2 in-----> 148 ft+0.17 ft------> AB=148.17 ft


AC=AB*cos 56°----> AC=148.17*cos 56°------> AC=82.86 ft


convert 0.86 ft to in

0.86 ft=0.86*12-----> 10.32 in

distance AB=82 ft 10 in


the answer is

the distance from the surveyor to the building is 82 ft 10 in

Shawna reduced the size of a rectangle to a height of 2 inches. What is the new width if it was originally 24 inches wide and 12
AfilCa [17]

Answer:

Step-by-step explanation:

Original Ratio              =                  New Ratio        All these problems are done the same way. Try to conquer the language.

The original ratio = 24 inches wide / 12 inches tall

Shawna's new ratio = you don't know / 2 inches in height (or tall)

Call what you don't know = x

24/12 = x / 2                        Cross multiply

12 * x = 24 * 2                     Combine the right

12 * x = 48                           Divide by 12

12x/12 = 48/12

x = 4

So the new height is 4 inches.
