You know that BC is congruent to x so you need to solve for x using the ratio: [latex]frac{12}{24}=frac{x}{BC}[/latex] So then we need to find BC. We know: [latex]A=frac{base imes height}{2}[/latex] [latex]28=frac{BC imes 7}{2}[/latex] Therefore BC =8 Then: [latex]frac{12}{24}=frac{x}{8}[/latex] [latex]x=8 imes frac{12}{24} = 4[/latex]
