an older person is three years older than seven times the age of a younger person the sum of their ages is 43 find their ages

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

boxplot e is the answer

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

y - 25 = 2 ( x - 10 ) should be the answer
