Answer:
The height of the bridge is 71.47 m.
Step-by-step explanation:
Since the eye of the surveyor is 1.45m creating the horizontal distance, we must add the 1.45 m to the 70.02 m to determine the total height of the bridge.
70.02 m + 1.45 m = 71.47 m
The height of the bridge is 71.47 m.
Step-by-step explanation:
Solution given:
By using Pythagoras law
h²=p²+b²
15²=x²+9²
x²=15²-9²
x=√144=12
x=12 is your answer
Answer: -2
Y = x(x+3)
Y = (-2)((-2)+3) * Distribute*
Y = 4 - 6
Y = -2
