Determine if the two figures are similar. identify pairs of congruent angles and corresponding sides. if the two figures are similar, identify the scale factor.

What basic trigonometric identity would you use to verify that sin x cos x tan x =1-cos^(2)x?

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.
