Answer 1

Answer:

y=5 in. x=2.5 in.

Step-by-step explanation:

figure out the ratio of sides between the triangles.

4 in. and 2 in. are a pair, 5 in. and x in. are another pair and y+1 in. and 3 in. is the last pair.

looking at 4 in. and 2 in. the ratio is 1/2.

multiply 5 by 1/2 to get x.

5*1/2=2.5           x=2.5 in.

since we know what the ratio is going from the bigger triangle to the smaller triangle, the reciprocal of the ratio will take us from the smaller triangle to the larger one. the reciprocal of 1/2 is 2. taking this information multiply 3 by 2 to get y+1.

3*2=6

y+1=6

y=6-1

y=5 in.
