If m A = 81 +14 and m2B= 22 + 50, what is mZB?

Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

An angle that measures between 90 and 180° is called a(,

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
