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.
R=r1+r2
simple
all you have to do is leave r2 by itself...
(r2=??)
by doing so you need to subtract r1 on both sides
R-r1=r2
and by doing so you leave r2 by itself
r2=R-r1

Answer: 3 and 8
Step-by-step explanation:
5 and 6 only apply to line M, 2 and 4 only apply to line M, while 3 and 8 apply to both.
(x , y) = (-4 , 6) There you go
Ok the answer is -5 less than 9 which is true lol
Anyways here’s how I got the answer
-5+7+2x-13 less than 9
Combine like terms in this case it’s -5 and 2, and the other is 7 and -13
-5+2= -3
7-13= -6
Ok now that that’s done here’s the next step
-3x-6 less than 9 solve it
-3x-6 < 9
+6< +6
-3x < 15
Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5
And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)
