Answer:
<em> (1). x = 14 ; (2). 70°</em>
Step-by-step explanation:
<em>(1).</em> m∠ACD = m∠A + m∠B
6x + 2 = (2x + 1) + (3x + 15)
6x - 5x = 14
<em>x = 14</em>
<em>(2).</em> m∠ABC = 180° - m∠CBD = 140°
<em>m∠A</em> = m∠C = 140° ÷ 2 = <em>70°</em>
<span>2 x - 6 = 20, where x is the temperature in degrees Farhenheit 6 hours ago. 2 x = 20 + 6, 2 x = 26, x = 26 : 2, x = 13 degrees F. We can prove it: 13 * 2 - 6 = 26 - 6 = 20 degrees F ( the current temperature ) Answer: The temperature 6 hours ago was 13 degrees F.Hope this helps.
