Answer:
HCF (HIGHEST COMMON FACTOR) OR GCF ( GREATEST COMMON FACTOR) OF 40 AND 60 IS 20.
Complementary
Step-by-step explanation:
Complementary Angles add up to 90°
Supplementary Angles add up to 180°
60 + 30 = 90
x=-58
jn=ln nk=nm
because
7 = s²
s = x + 2
7 = (x + 2)²
7 = (x + 2)(x + 2)
7 = x² + 2x + 2x + 4
7 = x² + 4x + 4
x² + 4x = 3
