Answer:
hmm i have no idea can u send a clear pic of question?
Answer:
90°
Step-by-step explanation:
EG is a straight line
EG = EHD + DHG
DHG is a 90 degree angle
180 = EHD +90
Subtract 90 from each side
180-90= EHD +90-90
90 = EHD
The arc has the same measure as the angle since it is from the center
arc ED = 90
Answer: Height at which the wire is attached to the pole is 12 feet.
Explanation:
Since we have given that
Length of the wire = 20 feet
Let the height at which wire is attached to the pole be h
and distance along the ground from the bottom of the pole to the end of the wire be x+4
Now, it forms a right angle triangle so, we can apply "Pythagorus theorem".

But height cant be negative so, height will be 12 feet.
Hence, height at which the wire is attached to the pole is 12 feet.
The sixth number should be 16 in order for the mean to be 12
Answer:
55 pirates for 5 ships, 121 pirates for 11 ships
Step-by-step explanation:
for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121
