Assume 3 breads are all different, 3 meats are all different and 2 cheeses are all different. A sandwich contains a type of bread, a type of meat and a type of cheese. The number of different types of sandwiches that can be made is
The correct choice is (C).
Answer:
Length of side of rhombus is
Step-by-step explanation:
Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.
It is also given that AB=a and AC=b
Let side of rhombus is x.
In ΔCEF and ΔCBA
∠CEF=∠CBA (∵Corresponding angles)
∠CFE=∠CAB (∵Corresponding angles)
By AA similarity rule, ΔCEF~ΔCBA
∴ their sides are in proportion

Hence, length of side of rhombus is
