Answer:

Place the compass point on vertex Y and draw an arc that intersects YX and YZ

Step-by-step explanation:

Given the construction of dividing an angle inteo two equal parts.

we have to find the first step of construction.

As seen in figure the angle ∠XYZ is dividing into two equal parts.

The first step of construction is to place the needle of compass at Y and draw an arc that intersects YX and YZ.

Hence, the correct option is option C.

Place the compass point on vertex Y and draw an arc that intersects YX and YZ

Bogdan [553]

Answer:

The answer to your question is:

x = -8; y = 1 ; z = -4

Step-by-step explanation:

Δ = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

  = 40 + 24 + 18 - (-4 + 45 - 96)

 = 82  + 55

 = 137

Δx = \left[\begin{array}{ccc}60&1&-4\\-12&4&3\\-52&-3&-2\end{array}\right]

= - 480 - 144 - 156 - ( 24 - 540 + 832)

= -780 -316

= - 1096

Δy = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

= 40 + 24 + 18 - ( - 4 + 45 - 96)

= 82 + 55

= 137

Δz = \left[\begin{array}{ccc}-5&1&60\\2&4&-12\\6&-3&-52\end{array}\right]

= 1040 - 360 - 72 - ( - 104 - 180 + 1440)

= 608 - 1156

= -548

x = -1096/ 137 = -8

y = 137 / 137 = 1

z = -548 / 137 = -4
