Sort by:

Label the vertices of the triangle A, B, C, with A at the top, B at the bottom left, C at the bottom right. Let the lines be BE and CF, where E, F are on lines AC and BC respectively. Let O be the point of intersection. Draw AO, which splits x into 2 triangles, with area y and z.

Hint: Apply the fact that for two triangles with the same height, the ratio of their areas is equal to the ratio of their base. Staff · 1 year, 9 months ago

YES, you have to find x. 'x' is a area of the figure (that small portion). Moreover, all the measures given are in sq. units. · 1 year, 9 months ago
