Answer: b= 3; 9= 18
Step-by-step explanation:
You can use the length of the triangles’ base to find the scale factor.
15/5 = 3.
now that we know the scale factor, just use it to determine b and a.
to find a, multiply 6 by the scale factor because the bigger triangle was scaled up
6x3=18 a=18.
to find b, divide 9 by the scale factor because the smaller triangle is being scaled down by 3 compared to the bigger one.
9/3=3 b=3.
you should have your answer by now.
