Sarah and her friends decide to plant a tree. They tie a rope exactly halfway up the tree to keep the tree vertical. If the rope is pulled tightly, it forms a angle with the ground. Assuming the tree is inches tall, the distance from the base of the tree to the position where the rope is staked into the ground is blank inches. (Round to the nearest tenth.)

Step-by-step explanation:

Calculating tree height requires the use of basic trigonometry: h = Tan A x d, where h is the tree height, d is the distance from tree, and A is the angle to the top of the tree. Since your measurements will be made at eye level, you need to know your eye height (height of your eye above the ground).

answer: the value of x is 7cm
