Question

construct a triangle DEF in which DE = 6cm, E = 45° and F = 60°.​

Answer 1

Answer:  Step-by-step explanation:  Draw a line of 6 cm,and mark it as DE  measure 45° make line   sum of triangle = 180   therefore , angle D =180-(45+60)                                  =   180-105                                   =  75°  then measure 75° on D  extend the line D and E  then it meet on a point
