Im not sure im in geometry

Answer 14

with respect to the 45 degree angle, we can add these labels

Answer 15

yes since tan(angle) = opp/adj

Answer 16

it might help to evaluate tan(45) first

use this calculator

http://web2.0calc.com

to find the value of tan(45) and tell me what that is

Answer 17

so tan(45) = h/100 is the same as 1 = h/100

Answer 18

100

Answer 19

this is a 45-45-90 triangle with congruent legs
