15^ is equivalent to 0.15, or 15/100. If you divide both numerator (15) and denominator (100) by 5, you get 3/20.
28% corresponds to 0.28. What fraction would that be?
Come on. Show your stuff.
The correct answer would be the first choice. For each picture drawn, the total cost increases by $34.50.
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
