(a)

Answer to Problem 13STP
The centre of the coordinate
Explanation of Solution
Given:
Concept used:
A perpendicular from the centre to the chord bisects the chord.
In right
Distance or radius cannot be negative.
Calculation:
Consider the following figure:
As centre is equidistance from all the points from the boundary of the circle therefore locate the centre.
Therefore, the centre of the coordinate

The radius of the circle is
Explanation of Solution
Given:
Concept used:
Perimeter of the shape having sides are the sum of all distance of the respective sides.
In right angle triangle Pythagoras theorem can be used as:
Distance or radius cannot be negative.
Calculation:
The radius of the circle is
(c)

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. 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_forward1arrow_forward
