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.

Solve R=r1+r2 for r2
Sphinxa [80]
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

-5x+7+2x-13&lt;9 Please Explain
olganol [36]
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)
