Question

In a right-angled triangle the difference between two acute angles is 2π/5. Express these two angles in terms of radian and degree.​

Answer 1

hiii

your answer is here !

Step-by-step explanation:

Let the acute angles be x^c and y^c. (According to the condition of the problem:

x + y = π/2 and x - y = 2π/5

Solving these two equations we get;

x = 1/2 (π/2 + 2π/5)

x = 1/2 (5π + 4π/10)

x = 1/2 (9π/10)

x = 9π/20

and y = 1/2 (π/2 - 2π/5)

y = 1/2 (5π - 4π/10)

y = 1/2 (π/10)

y = π/20

Again, x = (9 × 180°)/20 = 81°

y = 180°/20 = 9°
