The complete question in the attached figure
we know that
<span>The measure of the external angle is the semidifference of the arcs that it covers.
so
</span><span>m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2</span>m∠BED
mBD=80-2*25--------> mBD=30°
the answer ismBD=30°
City A and City B are about 76.5 miles apart because 51*1.5 = 76.5
Answer:
Option A is the correct answer.
Step-by-step explanation:
The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.
The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.
For a pentagon n =5.
Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°
Option A is the correct answer.
The given expression is undefined when x = 5 OR x = -5
<h3>Undefined expression </h3>
From the question, we are to determine the value of x for which the given expression is undefined
The given expression is
x-4/3x²-75
An expression is undefined when the denominator equals zero
Thus, the expression is undefined when
3x² - 75 = 0
Now, we will determine the values of x in the equation above
3x² - 75 = 0
3x² = 75
x² = 75/3
x² = 25
x = ±√25
x = ±5
Hence, the given expression is undefined when x = 5 OR x = -5

Answer:
Beatrice will accumulate $1230.72 at the end of the year.
Step-by-step explanation:
We can write:
for deposits
The first month would have only the deposit reflected in her balance, then, expanding some steps of the calculation would yield:
A geometric series is given by:
Translating our series to the short form:
plugin in the values for the 12 month gives:
