l a2 b2 is c2!!Its completely norma
144 Formula: c= (a2)+(ab)
Pythagoras says: a2 + b2 = c2 so a2 + 8.52 = 12.62 a2 = 158.76 - 72.25 a = sqrt(86.51) a ~= 9.3
A2 + B2 = C2 If C=8, then A2 + B2 = 64

a^2 - 16 = 48 a^2 = 48 + 16 a^2 = 64 a = square root(64) a = +8 or -8
l a2 b2 is c2!!Its completely norma
A squared = 6x6 = 36 B squared = 8x8 = 64 Square root of 36+64 = 10 Given: a2 + b2 = c2 a = 6 and b = 8. We need to find the value of c. a = 6 implies a2 = 62 = (6*6) = 36. b = 8 implies b2 = 82 = (8*8) = 64. a2 + b2 = c2 implies 62 + 82 = c2 c2 = 36 + 64 c2 = 100 c2 = 102 c = 10
144 Formula: c= (a2)+(ab)
* a2 + b2 = c2 * a = 3 * b = 8 * (3)2 + (8)2 = c2 * 9 + 64 = c2 * 73 = c2 * c = √73
a=3
A formula starts with an equals sign. A formula can be a function or contain functions with other aspects of the calculation. =B10+B15 =SUM(A2:A20) =MAX(A2:A20)+100 =MAX(A2:A20)-MIN(A2:A20)
Pythagoras says: a2 + b2 = c2 so a2 + 8.52 = 12.62 a2 = 158.76 - 72.25 a = sqrt(86.51) a ~= 9.3
