Solve for x please describe the steps 50 points
LuckyWell [14K]

Answer:

x = 6

explanation:

USE: \boxed{\frac{side-length }{base -length} = \frac{side-length}{base -length} }

solve:

\frac{21}{15} = \frac{7}{x-1}

21(x-1) = 7(15)

21x-21 = 105

21x = 105+21

21x = 126

x = \frac{126}{21}

x = 6
