Answer:
A) AS = 60
B) WE = 20
C) EN = 25
D) AR+RS-AS = 30
Step-by-step explanation:
Each midsegment is half the length of the parallel side. Each side is twice the length of the parallel midsegment.
A) AS = 2(WN) = 2(30) = 60
B) WE = RS/2 = 40/2 = 20
C) EN = AR/2 = 50/2 = 25
D) AR +RS -AS = 50 +40 -60 = 30
Answer:
7. m<K = 60
8. m<U = 110
9. m<C = 50
Step-by-step explanation:
Triangles: when all 3 angles all added it should be 180 degrees
7. 60+60+unknown value=180 --> unknown value=180-60-60=60
8. 35+35+unknown value=180 --> unknown value=180-35-35=110
9. 53+77+unknown value=180 --> unknown value=180-53-77=50
I think you forgot to insert a picture?
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
