What is the length of ab if bc=8m and m< a is 42 degrees? round to the nearest tenth of a meter.

In a right triangle, if AB is 8m and mA is 42 degrees, the length of AB would be 8.9 if B is the right angle, or 12 if C is the right angle.

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
