Is it SV squared? Or times 2
Answer:
5
Step-by-step explanation:
Verticle angles are the angles opposite of each side.
20x + 9 = 14x + 15
<span>6x = 6 </span>
<span>x = 1 </span>
<span> So base angles are 20 + 9 means 29 degrees. To calculate the m of angle k, subtract 29 from 180: </span>
<span>180 - 29 = 151 degrees.
