2.05 meters
Step-by-step explanation:
Superimpose a triangle when drawing out the situation. The distance the ladder reaches up the tree is the side of the triangle opposite of the angle. The distance the ladder is from the tree is side adjacent to the triangle. We can use tangent to solve this.
Tan X = (opposite side)/(adjacent side)
Tan 64 = a/1
Tan 64 = a (anything over 1 is just itself)
2.050303842 = a (use tan on your calculator)
Your answer is 89.56 hope this helps and God bless you
