Answer:

(x, y) = (22, 35)

base angle theorem; angle sum theorem

Step-by-step explanation:

Base angles theorem:

Angles opposite congruent sides are congruent:

3x -11 = 2x +11

x = 22

Angle sum theorem:

The sum of angles in a triangle is 180°.

(3x -11)° +(2x +11)° +2y° = 180°

5x° +2y° = 180°

2y = 180 -5(22) . . . . . divide by °, subtract 5x, substitute for x

y = 35 . . . . . . . . . divide by 2

Step-by-step explanation:

theodolite is a precision instrument that is used to measure the angle in the horizontal and vertical planes and it is the most commonly used in surveying.

A modern developed theodolite consists of a movable telescope that is mounted within two perpendicular axes called the horizontal axis and the vertical axis. Pointing the telescope on a target object will enable measurement of angle with great precision.
