2+6+18+54+162+486+1458+4375=6561
you multiply the previous number by three to find the next value
Answer:
Step-by-step explanation:
Comment
If two secants intersect outside a circle (as these two do) then the angle at which they meet is 1/2 the difference between the intersected arcs. Put much simpler <DCF = 1/2 (arc EG - arc DF)
Givens
Arc EG = 127
Arc DF = 49
Solution
<DCF = 1/2(127 - 49)
<DCF = 1/2(78)
<DCF = 39
Answer:
85%
Step-by-step explanation:
Monday:
200 x 0.70 = 140
200 - 140 = 60
Tuesday:
400 x ? = 60
400 x 0.85 = 340
400 - 340 = 60
