1. The Side Angle Side (SAS) similarity theorem states that:
If two sides of a triangle are proportional to 2 sides of another triangle, and the angles around each of these 2 pairs f sides are equal (congruent), then the triangles are similar.
2. That is, we notice the equivalent ratios:

so

then if m(I)=m(F)=60°, the triangles EFG and HIJ are similar, by SAS similarity theorem.
Answer:
−18y+48
Step-by-step explanation:
Well I thing is -99%. Might not be right. Hope it helps
Mark has 9. Chole has 2. Altogether, they have 11. Chole had 6, but gave away 4, leaving her with 2. Mark gets 4 apples to add to his 5, giving him 9.
