In the figure below
1) Using the theorem of similar triangles (ΔBXY and ΔBAC),

Where

Thus,

thus, BC = 7.5
2) BX = 9, BA = 15, BY = 15, YC = y
In the above diagram,

Thus, from the theorem of similar triangles,

solving for y, we have

thus, YC = 10.
Answer:
1:1 ratio
Step-by-step explanation:
a 1:1 ratio happens when the amount of the item is the same as the other. 1/4 cup of all purpose flour is the same amount as 1/4 rice flour so the recipe uses a 1:1 ratio
Answer:
subject?
Step-by-step explanation:
Answer:

Step-by-step explanation:
This answer is easily found using the Pythagorean Theorem:

where A and B are the legs, and C is the hypotenuse of the triangle.
