a, Xét \(\Delta\)ABC có: AB2 + AC2 = 62 + 4,52 = 56,25 (cm2)
BC2 = 7,52 = 56,25 (cm2)
AB2 + AC2 = BC2 vậy tam giác ABC vuông tại A (đpcm)
SinC = 6 : 7,5 =0,8 ⇒ \(\widehat{C}\) = 53,130 ⇒ \(\widehat{B}\) = 900 - 53,130 = 36,870
b, Dựng hình chữ nhật ABCD, chiều cao AH, DK, và đường thẳng d đi qua D song song với BC như hình vẽ ta có
SABC = SBDC ⇒ AH = DK
Lây 1 điểm bất M kỳ di động trên đường thẳng d ta có:
SBDC = SMBC (vì hai tam giác có chiều cao bằng nhau và chung cạnh đáy BC)
⇒ SABC = SMBC
Kết luận khi M di động trên đường thẳng d thì diện tích tam giác MBC luôn bằng diện tích tam giác ABC
