Two triangles are similar if they have:
<span>all their angles equalcorresponding sides are in the same ratio</span>
But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough.
There are three ways to find if two triangles are similar: AA, SAS and SSS:
Answer:
The value of x = 3.5 or -4
Step-by-step explanation:
=> 2x² = 28 – x
=> 2x²+ x - 28 = 0
=> 2x² + 8x - 7x - 28 = 0
=> 2x ( x + 4 ) - 7 ( x + 4 ) = 0
=> (2x - 7 ) ( x + 4 )
=> x = 7/2 = 3.5 or x = -4
13/36 would be the answer I believe
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor 
because it's the power of s with the smallest denominator. So, we have
