A fish market advertises fresh fish for $4.62 per kilogram. The original price was $5.25 per kilogram. By what percentage did the
price decrease?
a) 6.3%
b) 8.3%
c) 12.0%
d)13.6%

6.3%

Step-by-step explanation:

$5.25 - $4.62 = 0.63. Which basically means 6.3% in this case. I think-

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
