Step-by-step explanation:
We will follow the following steps for converting a ratio into a percentage:
Step I: Obtain the ratio. Let the ratio be x : y
Step II: Convert the given ratio into the fraction x/y.
Step III: Multiply the fraction obtained in step II by 100 and put the percentage sign(%).
Answer:
y > 2
Step-by-step explanation:
1) 
Divide both sides by <em>3</em>.
2) 
Move the constant to the right side and change it's sign.
3) 
Subtract the numbers.
4)

Answer:

Step-by-step explanation:
Given: ∠PTQ ≅ ∠STR and TP, TQ, TR and TS are radii of the circle.
If two angle are equal, then they are equal in size and their measurements are equal.
IF ∠PTQ ≅ ∠STR then they are also equal in their measurements.
Now, In ΔPTQ and ΔSTR
∠PTQ ≅ ∠STR (vertically opposite angle)
(Radius of the circle are equal and congruent in length)
(Radius of the circle)
∴ ΔPTQ ≅ ΔSTR (SAS postulate)
∴
(corresponding sides of congruent triangle are equal and congruent).
