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>
Answer: the first graph
Reasoning: When a graph is going left to right it is a decay while when it’s going right to left it is an increase... think of linear equations where if it is going from left to right the slope is negative, it’s the same for the exponential decay and increase.
