Answer:
Step 1: m<KHG + m<GHJ=180 degrees
Step 2: x=13
Explanation:
This pair of angles is called vertical angles. In a vertical angle situation, opposite angles are equal to each other. An opposite angle and an adjacent angle are ALWAYS equal to 180 degrees.
To start off...
Make both parts of the equation equal to 180 degrees
5x+38+7x-14=180
Combine like terms and add the regular numbers together
5x+7x and 38 + -14
12x+24=180
Subtract 24 from each side of the equation
12x=156
Divide 12 from each side.
x=13
