Best ResponseYou've already chosen the best response.0Let the length of the equal sides be \(x\) inches then: \(2x + x2 = 43 \implies 3x = 45 \implies x = 15 \) inches

Best ResponseYou've already chosen the best response.1We know that the sum of the three sides (the perimeter) is 43 inches. Let x = lenght of one of the equal sides then the base is x2 inches (given) lets add up the three sides x2 + x + x which is 3x2 and equal to 43 3x2 = 43 3x=45 x=15 in. the equal sides are 15, and the base is 152 or 13 inches.
