Question

A geologist at point A measures the distance and angle of elevation to two

columns of the Glen Rose formation in Texas. If the distance AS = 790ft and the distance AN = 883ft, compute the difference in the heights of the two columns to the nearest foot.

[A] 1 ft [B] 970 ft [C] 260 ft [D] 118 ft

Answer 1

I am so confused... Idk what to do...

Answer 2

Is there a picture that goes with this?

Answer 3

Answer 5

sin(49) = length of SB/length of AS
sin(54) = length of NC/length of AN

Answer 6

oh ok..

Answer 7

How would I find the length of SB?

Answer 8

what is the length of AS?

Answer 9

790

Answer 10

great! so you can use my equation to find the length of SB

sin(49) = length of SB/length of AS

Answer 11

put in the length of AS and solve for SB

Answer 12

Ok, let me try.

Answer 13

make sure your calculator is in degree mode

Answer 14

Ok. Would I divide AS by sin(49?

Answer 15

How would that work?

Answer 16

not quite:

here's a hint:

a = b/c

b = c*a

Answer 17

ok..

Answer 18

596.2?

Answer 19

great!

now do the same thing for the second equation:

sin(54) = length of NC/length of AN

Answer 20

Sorry I was eating dinner

Answer 21

714.3

Answer 22

So the answer (final) would be D, correct?

Answer 23

yup! good work!

Answer 24

thank you!
