In the following right triangle, which one of the following show the value of tan(theta) and sec(theta)? Triangle 90degree
AB = 4
AC = 6
Angle C = theta
Angle B = 90 degree

A). (2√ 5)/5 and 3/ 2
B). (2√5)/5 and (3√5)/5
C). (√5)/2 and (3√5)/5
D). (√5)/2 and 3/2

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.
