48 miles per hour! Just double 30 minutes to get an hour, and double 24 as well which equals 48.
This is an isosceles triangle, therefore we have two sides with the same length.
This sides are JM and MK; therefore:
JM=MK
JM=9x-18
MK=3x
Therefore:
9x-18=3x
9x-3x=18
6x=18
x=18/6
x=3
Part A:
Answer: x=3
Part B:
JM=9x-18=9(3)-18=27-18=9
Answer: JM=9
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
Answer:
I believe that it is the 3 option Im not 100% sure but im most certain
