To prove:

Answer to Problem 4PSA
Explanation of Solution
Given:
Concept used:
If a radius perpendicular on a chord bisects the chord then triangle form is congruence to each other.
The reflexive property states that for every real number
Corresponding parts of congruent triangles are congruent
When triangles are congruent, one triangle can be moved to coincide with the other triangle. All corresponding sides and
Two triangles are said to be congruent if all the three sides and three angles are same.
Condition of congruence triangle:
Side angle side
Side-side-side
Angle side angle
Angle-angle side
two angle and non-included side between the angles of one triangle is equivalent to another two angle and non-included side between the angles of triangle.
Right angle hypotenuse side
Calculation:
According to the given:
Since, a radius perpendicular on a chord bisects the chord.
According to the reflexive property:
Therefore,
Since, congruent parts of congruent triangles are congruent.
By definition of angle bisector:
Hence,

Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward
