Answer: choice A) x = 60, y = 30
==================================================
Focus on the smaller triangle on the left side. This is an equilateral triangle with all angles the same measure. So we have three angles each x degrees. They add to x+x+x = 3x. Set this equal to 180 (all angles of any triangle add to 180) and solve
3x = 180
x = 180/3
x = 60
Since all three angles of that triangle are each 60 degrees, this means that the base angle of the smaller triangle on the left is y = 90 - x = 90 - 60 = 30.
Put another way, x+y = 60+30 = 90 because the angles x and y form the 90 degree right angle. See the attached image for more info.
note: the triangle on the right side is an isosceles triangle. The base angles are congruent, and these angles are opposite the congruent sides (marked with the tickmarks).
2 1/5 cups * 4 gallons =
2.2 cups * 4 gallons =
8.8 cups of syrup
Well, we know that cube has 6 sides
So, the least number of different colors needed to paint a cube so no adjacent faces have the same color is :
At least 3
Hope this helps
