Answer:
IM PRETTY SURE ITS 44
Step-by-step explanation:
I HOPE IM RIGHT
Standard form;
(x - 2)² + (y - 6)² = 49
the center-radius form of the circle equation is in this format;
(x - h)² + (x - k)² = r²
so the center of the circle is; (2, 6)
so the radius of the circle is; 7
hope that helps, God bless!
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>
