Question

If the ratio of the angles of a triangle are in the ratio $3:4:5$, then its angles (in degrees) are

• A. 45, 75, 90
• B. 48, 52, 80
• C. 45, 60, 75
• D. 45, 65, 70

Answer 1

Answer: (C)

45, 60, 75

If the ratio of the angles of a triangle is $3:4:5$, then its angles in degree will be

$\frac{3}{12}\times 180={45}^0$
$\frac{4}{12}\times 180={60}^0$
$\frac{5}{12}\times 180={75}^0$
