In the figure above, what is the ratio

Mohd Halim Bin Hisyam

In the question they did not specify, the triangle is a right triangle, where the angles within a right angle triangles are 90, 60, 30 degrees respectively. As such, this assumption will result to a wrong answer.

Sum of all internal angles of a triangle must be 180
(this is a 90 deg triangle)
Hence, Y + (Y + 10) + 90 = 180
Y = 40
angle B = Y = 40
angle A = (Y + 10) = 50

angle B/ angle A = 40/50 = 4/5
