Step-by-step explanation:
in tri ADC and tri BDC
∠ADC =∠BDC = 90
DC is common
AD = BD (given)
triangle ADC ≅ tri BDC by SAS congruency
hence AC = BC by CPCT ( congruent parts of congruent triangles)
hence, BC = 13
Hello:
an equation for the line is : y =mx +b (m: is a slope )
parallel to the liney=2x+2 ( same slope m =2)
the equation is : y =2x+b
through the point (-1,3) : 3 =2(-1)+b....... b=5
the equation is : y = 2x +5
