The figure below is a diagram that shows how Colleen estimates the height of a tree that is on the other side of a stream. She stands at point A facing the tree and finds the angle of elevation from A to the top of the tree to be 56°. Then she turns 100° and walks 25 feet to point B, where she measures the angle between her path AB and the line BC extending from her to the base of the tree. She finds that angle to be 38°. Use this information to find the height of the tree. (Round your answer to the nearest whole number.) ft A 25 ft

Tamara wants to calculate the height of a tree outside her home. Using her clinometer, she measuresthe slope angle from 30 feet away from the base of the tree and gets an angle of 62°. If Tamara’s eye levelis 5.5 feet above the ground, how tall is the tree?

The figure below is a diagram that shows how Colleen estimates the height of a tree that is on the other side of a stream. She stands at point A facing the tree and finds the angle of elevation from Ato the top of the tree to be 51°. Then she turns 105° and walks 25 feet to point B, where she measures the angle between her path AB and the line BC extending from her to the base of the tree. She finds that angle to be 38°. Use this information to find the height of the tree. (Round your answer to the nearest whole number.)

Bailey installs solar panels in Saskatoon. She adjusts the angle to match the season. In winter, the angle of elevation for panels in Saskatoon is 75.8°. The panels are 2.21 m tall. The roof is flat. How tall should the supporting brace be? 2.21 m In spring and fall, the panels from Question 4 will tilt to meet the brace at a height of 1.92 m. Draw a diagram. What will the angle of elevation be for spring and fall? supporting brace
