Answer:
x = 3
y= 1
Step-by-step explanation:
for x:
sin (60°) = x/2
x = (sin 60) × 2
x = √3
for y:
cos (60°) = y/2
y= 2 × (cos 60)
y= 1
1 1/3 + 1 2/3=3 or 1 1/2 +1 1/2=3
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).
