So here is how we are going to get the measure of angle 2. Since given that angle COE measures 55°, we will equate <span>m∠2 = 2x and m∠3 = x+10 with 55. So, 55 = 2x + x + 10 55 = 3x + 10 55-10 = 3x 45 = 3x << divide both sides by 3 and the result is 15 = x So now that we know x, we can now solve for angle 2. </span>m∠2 = 2x m∠2 = 2(15) m∠2 = 30<span>° I hope that this is the answer that you are looking for. </span>
