I believe this is scale factor? SF=new/old. 10/8= a scale factor of 1.25 (the image gets 1.25x bigger). To find x, multiply 5 by 1.25 and subtract the original length of 5 (you subtract this length because x is only the value of the new part of the triangle). X=6.25-5, X=1.25. Try to find y yourself using this scale factor. (Brainliest would be appreciated)
Multply both sides of the equation by 7.

_____
When the variable is in the numerator of a proportion like this, you can solve it by multiplying by that denominator. That multiplication cancels the denominator and gives you the value of the variable.
In general, you multiply by the reciprocal of the coefficient of x. When that coefficient is 1/7, you multiply by 7/1. Of course, you know that 7/7 = 1 and that x/1 = x.
Answer:

Step-by-step explanation:
As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.
So,

It is given as,
RC = 3.3
PR = 1.8
AC = 6.6
PQ = ??
Putting the values,


Ratio of areas of similar triangles is 9 : 25.
Solution:
Given data:
Ratio of sides of two similar triangles = 3 : 5
To find the ratio of areas of the triangles:
We know that,
<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>



Ratio of areas of similar triangles is 9 : 25.
Answer:
ΔMLN - ΔΡQO
Step-by-step explanation:
Therefore,due to the correct pattern ΔMLN - ΔΡQO is correct.
