Find b in the right triangle using the most direct method? a = 1, c = 8

solve the right triangle. a = 20.9 degrees and a = 11.3. what is b and b?

use the tangent function to find a if a = 34.3 degrees and b = 9 ft in the triangle abc.

solve the triangle abc if a = 36.4 degrees and c = 6.1 mm. find b, a, and b.

Aefg - almn. find the ratio of aefg to almn. a)1: 4 b)1: 2 c)2.1 d)4: 1

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.
