We have measures of all tree sides of the both triangles,
so we can use SSS to check if the triangles are similar.
|ED|/|AB| =5/10=1/2
|DC|/|BC| = 4/8 = 1/2
|EC|/|AC| = 6/12 = 1/2
We see that all tree pairs are in proportion, so these triangles ΔABC and ΔEDC are similar.
We have enough information to prove that ΔABC similar to ΔEDC.
The area of the rhombus is 65.79
If you square a number then get the square root of that, you end up with the original number.
Answer:a= square root of (c^2 - b^2)
Step-by-step explanation:
Subtract b^2 from both sides then take the square root of both sides
Answer:
Option is d) Coincident lines.
Step-by-step explanation:
Given:
x = 2 - y and
3x + 3y = 6
Solution:
Let we rewrite the equations as
x + y = 2 ...................................Equation ( 1 )
3x + 3y = 6 ....................................Equation ( 2 )
Compare the above Two Equations with the following
a₁x + b₁y = c₁ and
a₂x + b₂y = c₂
We get
a₁ = 1 ; b₁ = 1 ; c₁ = 2 and
a₂ = 3 ; b₂ = 3 ; c₂ = 6
Now we will check

Now we get

Which is the condition for a COINCIDENT LINES
COINCIDENT LINES have Infinite solutions for different x and different y
