Are these 3 separate questions?
Answer:
Step-by-step explanation:
<JKL = 90 ( being inscribed angle in semi circle )
< JKP = 38 ( Inscribed angles on same arc are equal )
So now
<PKL = <JKL - < JKP
= 90 - 38
= 52
FINALLY
ARC PL = 2 * < PKL (Relation between arc and inscribed angle )
ARC PL = 2 * 52
= 104
hope it helps :)
Keep change flip that's all you gat to do
The series in the form of arithmetic progression
The notation of A.P is a, a+d, a+2d.....
The summation notation is â‘
In this series a=3, d=7
Then the summation of A.P is â‘ = n/2(2a+(n-1)d)
=18/2(2*3+ (18-1)7)
= 9(6+17(7))
=9(6+119)
=9(125)
= 1125
Hence the total number of beads is 1125
