Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is distance between the top of the ladder and the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft
Feel free to ask for more if needed or if you did not understand something.
Then mark it down by less then 1%, of by whatever the number would be.

Answer:
11
Step-by-step explanation:
I think if I am wrong I am sorry
Add all the angle and =to 180 because all the angle in a triangle add up to 180 then put all numbers on one side and all x terms on the other side then you find x
