The answer is 7/5. I attached the work below.
Answer:
.0000111
Step-by-step explanation:
move the decimal five places to the left because the 5 is negative

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°






The required value of x is 7°
let x be how far up the wall ladder reaches
by Pythagoras theorem
x^2+5^2=13^2
x^2 =(13^2)-(5^2)
x= square root of 144
x= 12 or x =-12(rej,x>0)
hence ladder reaches 12 foot up the wall
