Answer 1

Answer:

Take one angle as 'x' & the other as 'x-30°'.

Step-by-step explanation:

So, we get the equation as,

x + (x-30°) = 90° [ since, complementary angles add up to 90°]

x+x - 30° =90°

2x = 90° + 30°. [ transposing]

x = 120°/2

Therefore, x = 60°.

x-30°= 30°

Hence, angle which is 30 degrees less than it's complement is, 30°.

Hope it helps.
