If $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50​ Asap

Step-by-step explanation:

When you do 45 divided by 9 you get 5.

                         45 / 9 = 5

     To figure out what the smaller number (in this the 4) equals,

  you have to do 4 times 9 to get 36.

                    4 * 9 = 36

So your answer is 36.

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.
