Answer:
x-coordinate is the first element in an ordered pair.
0.035 + x = 4.036
get x on its own
x = 4.036 - 0.035 = 4.001
so 4.001 is added
Answer:
c and d
Step-by-step explanation:
Answer:
292.45 m
Step-by-step explanation:
Both disk are at an angle of 38.48°
From the image below we calculate as,
For disk B, direct distance is 1.296 km from receiver = 1296 m
Vertical height from ground will be = 1296 x sin38.48 = 806.42 m
For disk A, direct distance is 826 m from receiver
Verival height above ground = 826 x sin38.48 = 513.97 m
Difference in height between disks is 806.42 - 513.97 = 292.45 m
