SAS, SSS, SSA all prove the congruency of the two triangles.
Number 1.
2x to the second power minus 2x minus 4
Number 2.
2a to the second power minus 3b minus a plus b to the second power.
Hope it helped :)
FVAD=8000[((1+0.10/4)^(4*4)-1)/(0.10/4)]*(1+0.10/4)
FVAD=158917.84
This would be no solution , there is none
