Answer:
53 degrees
Step-by-step explanation:
Angle N = angle E
because angle made by joining end points of same chord on circumference are always equal.
so angle E = 37
Angle D = 90 ( because angle made by diameter on circumference is 90 degrees)
Now in Triangle DEC. Sum if all the angles of triangle us 180
Angle D + angle E + ? = 180
37 + 90 + ? = 180
127 + ? = 180
? = 180 - 127
? = 53 degrees
20, because 5 there and five back then 1 and 1 back and four and four back if not then just add all 5+4+1=10
Height:shadow=2.5:3
2.5/3=6.7/x
cross multiply aka times both sides by 3x
2.5x=20.1
divide both sides by 2.5
x=8.04
answer is 8.04ft
The answer is 15840 and 10920
