One angle measures [tex]\( 170^{\circ} \)[/tex], and another angle measures [tex]\( (6k + 44)^{\circ} \)[/tex]. If the angles are vertical angles, determine the value of [tex]\( k \)[/tex].

A. [tex]\( k = 12 \)[/tex]
B. [tex]\( k = 20 \)[/tex]
C. [tex]\( k = 21 \)[/tex]
D. [tex]\( k = 126 \)[/tex]



Answer :

Vertical angles are angles opposite each other formed by two intersecting lines. These angles are always equal. Given this, we know the two angles are equal, i.e.,

[tex]\[ 170^\circ = (6k + 44)^\circ \][/tex]

To determine the value of [tex]\( k \)[/tex] that satisfies this equation, follow these steps:

1. Set up the equation:

[tex]\[ 170 = 6k + 44 \][/tex]

2. Isolate the variable [tex]\( k \)[/tex]:

[tex]\[ 170 - 44 = 6k \][/tex]

3. Simplify the left side:

[tex]\[ 126 = 6k \][/tex]

4. Solve for [tex]\( k \)[/tex]:

[tex]\[ k = \frac{126}{6} \][/tex]

5. Calculate the value of [tex]\( k \)[/tex]:

[tex]\[ k = 21 \][/tex]

Therefore, the value of [tex]\( k \)[/tex] that satisfies the angle equation is

[tex]\[ k = 21 \][/tex]
