41.848/3.4=12.308
The actual building is 12.306 times larger than the model.
Answer:
A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line.
Step-by-step explanation:
See the picture to better understand the problem
we know that
in the triangle ABC
∠A+∠B+∠C=180°
∠C=180-(86+69)-----> ∠C=25°
Applying the law of sines
b/sin B=c/sin C------> b=c*sin B/sin C-----> b=82*sin 69/sin 25
b=181.14 ft
the answer is181.14 ft
3(4m-2) -2(m+5)
12m -6 -2m -10
10m -16
answer is 10m -16 :)
