    First let us prove that the two triangles are congruent. <BAC=<FDE AC=DF <ABC+<DEF Therefore the two triangles are congruent by ASA. Nw since they are congruent BC=EF 3x+2=4x-6 2+6=4x-3x x=8 So BC=3*8+2=24+2=26 Is it clear?

    Look at the two triangular sign boards below. Which pair of equations is correct? x = 70 and y = 55 x = 3 and y = 65 x = 4 and y = 4 x = 4 and y = 50

    Here too the triangles are congruent. so y+5=55 y=55-5 y=50 15x+10=70 15x=70-10 15x=60 x=60/15 x=4
