Lenny is planning to cut down a pine tree. he has parked his truck 90 feet away from the base of the tree and wants to make sure that the tree will not hit his truck when it falls. the angle of elevation from the base of the truck to the top of the tree is 50°. how tall is the tree to the nearest foot? should lenny move his truck?

Question 101 points)which equation in slope-intercept form represents the line that passes through (5, 1) and(-4,7)

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
