The external angles of a 12-gon add up to 360 degrees so each is 30 degrees. That makes the internal angle the supplement, PQR=150 degrees.
We have an isosceles triangle so the other two angles add to 30 degrees, so 15 degrees.
Answer: 15 degrees
Answer:
(5 , 3)
Step-by-step explanation:
The midpoint = (3+7)/2 , (9-3)/ 2
= 10/2, 6/2
= (5 , 3)
Probability that the device doesn’t work properly is all parts not working.
That would be 1/2^6 = 1/64
Probability the device works is
1 - probability device doesn’t work
1 - 1/64 = 63/64
63/64 is probability device will work
