Answer:
ok
Step-by-step explanation:
<span>4*5/2 = 10
5*5/2 = 25/2 = 12/5
The poster is 10 x 12.5 inches. </span>
Answer:
They are equivalent
Step-by-step explanation:
We can do cross products for this one
17/3 = 68/12
17 times 12 = 68 times 3
204 = 204
What are the theorems we can use?
Probably the most relevant is the angle at a point on the circle subtended by a chord has a measure equal to half the arc indicated by the chord.
By the theorem,
angle AEB = angle ADB = (1/2) arc AC = (1/2) 110 = 55 deg
angle BAE = angle DBE = (1/2) arc DE = (1/2) 130 = 65 deg
angle BKD + angle KDB + angle DBK = 180 deg
angle BKD + angle ADB + angle DBE = 180 deg
angle BKD = 180 - 55 - 65 = 60 degrees
Answer: 60 degrees
