Pythagorean Theorem, c2 = a2 + b2, can be used to find a missing side of a right triangle. If c = 14 and a = 10, which equation can be used to solve for b?
I would say this is the answer: You can put this solution on YOUR website! a right triangle has 2 legs and a hypotenuse. the hypotenuse is opposite the 90 degree angle. the 2 legs are opposite the other angles of the triangle. if you know 2 of the dimensions then you simply use the formula to solve for the remaining dimension. assume one of the legs is equal to a and the other leg is equal to b and the hypotenuse is equal to c. then the formula is: c^2 = a^2 + b^2 suppose you know the value of a and b you substitute for a and b in the equation and solve for c. assume a = 6 and b = 8 the formula becomes: c^2 = 6^2 + 8^2 = 36 + 64 = 100
now you take the square root of both sides of the equation to get: c = sqrt(100) = 10 now suppose you knew that c was equal to 10 and a was equal to 6. your equation of: c^2 = a^2 + b^2 becomes: 10^2 = 6^2 + b^2 which becomes: 100 = 36 + b^2 you subtract 36 from both sides of the equaton to get: 100 - 36 = b^2 you simplify to get: 64 = b^2 you take the square root of both sides of the equation to get: 8 = b
