A hot-air balloon floating at 950 m/h at a constant altitude of 3000m is observed to have an angle of elevation of

78º. After 20 minutes, the angle of elevation is 73º.

Calculate the angle through which the observed gas turning during those 20 minutes.

Evaluate the given expression if m=45 |-3m|

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

The vertices of a triangle are a(7,5), b(4,2), c(9,2). what is m
