The question requires us to find out by how much did Kendra increased her distance every day:
The first day she hiked 1/8 miles
the second day she hiked 3/8 miles
third day she hiked 5/8 miles
this can be written as arithmetic sequence given by:
1/8,3/8,5/8,...
the arithmetic difference will be:
3/8-1/8=5/8-3/8=2/8
This means that Kendra increased her daily distance by 2/8 miles

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
