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
Answer: 102
Step by Step Explanation:
5y+11=8y-13
-8 -8y
-3y+11=-13
-11 -11
<u> 3y </u>=<u> -24</u> = 8 y=8
3y 3y
5(8)+11=51
Multiple 51 times 2 and you're answer will be the following.
Let x = 0.25555…
10x=2.555…
9x=2.3
90x=23
x=23/90
Answer:
A
Step-by-step explanation:
multiply 9 by 12 to get the surface area of the end of the rectangle.
you should get 108.
multiply 12 by 9 to get the surface area of the side.
you should get 135.
multiply 12 by 15 to get the surface area of the bottom.
you should get 180.
then add all your answers and multiply by 2 this will give you the total surface area and you will find that the answer is A.
