Given: △dmn, dm=10 square root 3, m∠m=75°, m∠n=45° find: perimeter of △dmn

The answer to your question:  Perimeter = 62.19 m

Step-by-step explanation:

Data

DM = 10 √3

∠M = 75°

∠N = 45

Perimeter = ?

Process

The sum of the internal angles in a triangles equals 180°

                        ∠D + ∠M + ∠N = 180

                          ∠D = 75 + 45 = 180

                           ∠D = 180 - 120

                            ∠D = 60°

D =

D = 21.21      

}" alt="\sqrt{3}" />}" />

D =

D = 23.66

Perimeter = 21.21 + 23.66 + 10

Perimeter = 62.19 m
