Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
A <u><em>circumscribed angle</em></u> is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so

Find the measure of angle BAC
In the right triangle ABC

substitute given value


Find the measure of angle BAD


Find the measure of minor arc BD
we know that
-----> by central angle
therefore

Answer: a) $2155, b) $1763.03.
Step-by-step explanation:
Since we have given that
Number of cable knit sweaters = 15
Cost per sweaters = $65.00
Number of pairs of khaki twill pants = 22
Cost of each pair = $50.00
Number of casual jackets = 18
Cost of each jackets = $62.00
total sale volume would be

Employee discount = 35%
Additional discount = 15%
So, Total markdown dollars taken is given by

Hence, a) $2155, b) $1763.03.
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>We have similar triangles here.</u>
- BC║DE, AB║AD and AC║AE ⇒ ΔADE ~ ΔABC
<u>The ratio of corresponding sides of similar triangles is same:</u>
- BC/DE = AC/AE
- BC / 2 = 30/3
- BC / 2 = 10
- BC = 2*10
- BC = 20 m
