Sholpan [36]
See the attached figure to better understand the problem

we know that

in the triangle ABC
tan 15=AC/BC--------> AC=BC*tan 15
BC=51 m
AC=51*tan 15------> AC=13.67 m

t<span>he height of the shorter building=207-AC----> 207-13.67----> 193.33 m
</span>the height of the shorter building=193 m
<span>
the answer Part a) is
</span>the height of the shorter building is 193 m
<span>
Part b) </span><span>how does the angle of depression from the top of the taller building relate to the angle of elevation from the top of the shorter building
</span>
we know that

the angle of depression is equals to the angle of elevation
so

the answers are
<span>A:They are congruent
</span><span>D:They are alternate interior angles</span>

Subtracting fractions with unlike denominators
lawyer [7]

Answer:

3/12 or simplified 1/4

Step-by-step explanation:

First make the denominators the same. We can make 12 the common denominator. To make 3/4 have a denominator do the following:

Multiply the numerator and denominator by 3 since 4x3=12. The new number becomes 9/12.

Then subtract:

9/12-6/12=3/12  The numerator subtracts while the denominator stays the same.

We can simplify 3/12 to 1/4

Factor out the coefficient of the variable 1/2d+6
IrinaK [193]
Factoring out the 1/2 (that is the coefficient of the variable) would require you to divide the equation by one half, which is the same as multiplying by two. After doing this, the answer can be expressed as:

1/2 (d+12)
