Answer:
3.5 inches
Step-by-step explanation:
We can rotate the figure to the left 90 degrees clockwise so that it becomes same orientation as the figure to the right.
Since they are similar figures, their corresponding sides are proportional.
The 4 inch side of left figure corresponds to 16 in side of right side figure.
The "?" inch side of left figure corresponds to 14 in side of right side figure.
We can replace "?" with "x" and setup two ratios and equate them:

Now, we can cross multiply and solve for x:

Hence,
the unknown side marked "?" is equal to 3.5 inches
2 acute and 2 obtuse and 0 right angles
It is 21. Seven 1/7th's makes 7/7 which equals one. So multiply 7x3 and that is 21.
Tan(Θ)=(h/distance from base)
Θ=13 degrees, 1mile=5280 ft
tan(13)=(h/5280 ft)
5280tan(13)=h
h=1218.984049
h=1219 ft
We can determine the limit by direct substitution. f(-1) is 2, and thus that is the limit there. g(2), however, does not exist because the left and right limits do not agree
