Elena L [17]

Answer:

A theodolite

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.

Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli
Sergeeva-Olga [200]

Let <em>f(x</em>, <em>y</em>, <em>z)</em> = <em>z</em> - arctan(<em>x y</em>). Compute the gradient of <em>f</em> at the point (0, 3, 0):

∇ <em>f(x</em>, <em>y</em>, <em>z)</em> = (-<em>y</em> / (1 + <em>x</em>²<em>y</em>²), -<em>x</em> / (1 + <em>x</em>²<em>y</em>²), 1)

∇ <em>f </em>(0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface <em>z</em> = <em>f(x</em>, <em>y)</em>. Then the equation of the tangent plane is

∇ <em>f </em>(0, 3, 0) • (<em>x</em>, <em>y</em> - 3, <em>z</em>) = 0

(-3, 0, 1) • (<em>x</em>, <em>y</em> - 3, <em>z</em>) = 0

-3<em>x</em> + <em>z</em> = 0

<em>z</em> = 3<em>x</em>

Find the value of the variables in the figure below
svetlana [45]

Answer:

The answer to your question is:

x = 21

y = 4

∡ = 75° and 105°

Step-by-step explanation:

Process

            3(x + y)° + 5x = 180                  supplementary angles

            3(x + y) = 4x - 9                        corresponding angles

Expanding

           3x + 3y + 5x = 180       (1)           Like terms

           3x + 3y = 4x - 9            (2)        

          8x + 3 y = 180         (1)

    8   (   -x  + 3 y = -9)       (2)           Multiply by 8

       8x  + 3y = 180       (1)

      -8x +24y = -72        (2)                    Elimitation method

               27 y = 108

                  y = 108 / 27

                  y = 4        

         8x + 3 (4) = 180

         8x +12 = 180

               8x    =  168

              x = 21

             

3(21 + 4) = 3(25) = 75°

5(21) = 105°
