Ответ:
Congruent triangles have congruent sides and angles. If ΔKMN≅ΔPRT (given) then from the diagram you can conclude that
KM≅PR;MN≅RT;KN≅TP.If MN≅RT, then
3x-1=20,
3x=20+1,
3x=21,
x=21:3,
x=7.
x=7.
Ответ:
3x + 6(3) = 24
3x + 18 = 24
Then subtract both sides by 18:
3x + 18 - 18 = 24 - 18
3x = 6
Then, divide both sides by 3
3x/3 = 6/3
Simplify,
x = 2
