There Is a wild herd of 20 horses. 10 of those horses are brown, 5 of them are white, 3 of them are black, and 2 of them are white and brown. An hour later the herd ran 2 miles. The herd did this 3 times every day. How many miles do the horses run in one week?

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.

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.

M.xyz =radians. covert this radian measure to its equivalent measure in degrees.
