Answer:
The person casts a shadow 3 feet long.
The building casts a shadow 15 feet long.
The ratio of the person’s shadow to the building’s shadow is 1 to 5.
If the other side of the building is 10 feet tall, the person will be 2 feet tall.
<em>(I'm not sure what the last question meant by "the other side of the building". I assume it means the height of the building? 2 feet tall seems a bit short for a person though, but that would be correct since the building's height is 2/3 of the shadow's length, and 2/3 of the person's shadow length, 3, is 2 feet)</em>

C is 12 and x is 3 and that would be your variables
Answer:
Below
Step-by-step explanation:
All you need to do to find angle x is to subtract 48 from 90 :)
So, 90 - 48 = 42
Angle x = 42 degrees

The height of the mountain estimated by two students is 2,467.98 meters.
<h3>
Height of the mountain </h3>
The height of the mountain is calculated as follows;
tanα = h/( a + b + x)
where;
- x is the distance between end of b and h
tan37 = h/(1850 + 740 + x)
tan37 = h/(2590 + x)
h = tan37(2590 + x)
h =1,951.82 + 0.7536x ---- (1)
tanβ = h/(b + x)
tan60 = h/(740 + x)
h = tan60(740 + x)
h = 1,281.68 + 1.732x ---- (2)
Solve (1) and (2) together
1,951.82 + 0.7536x = 1,281.68 + 1.732x
1,951.82 - 1,281.68 = 1.732x - 0.7536x
670.14 = 0.9784x
x = 684.93 m
h = 1,281.68 + 1.732x
h = 1,281.68 + 1.732(684.93)
h = 2,467.98 m
Thus, the height of the mountain estimated by two students is 2,467.98 meters.

Answer: hello your question has some missing information attached below is the missing information
- we fail to reject H0 hence μ1 = μ2
- mean difference ( d ) = -2.444
Step-by-step explanation:
H0 : μ1 = μ2
Ha : μ1 ≠ μ2
where : μ1 = mean number of errors made in pretest
μ2 = mean number of errors made in post test
n = 9
attached below is the detailed solution
