Answer:
38 deg
Step-by-step explanation:
Angles A and M are corresponding angles of congruent triangles, so they are congruent.
m<A = m<M = 38 deg
Answer:
Step-by-step explanation:
240 has a reference angle of 60 in the third quadrant. The side across from 60 is going to be negative in this quadrant, measuring -√3; the side adjacent to the angle is also negative in this quadrant, measuring -1. The tangent ratio is the side opposite the angle over the side adjacent to the angle, so
tan(240) = √3
Perimeter means finding the total area of the outside of the triange (so the sum of all sides).
