Given one angle of a triangle is \(\frac{2}3x\) grades and another is \(\frac{3}2x\) degree while the third is \(\frac{πx}{75}\) radians.
We know that 1 grad = \((\frac{9}{10})°\)
We know that π rad = 180°
⇒ 1 rad = 180°/ π
Given \(\frac{πx}{75}\)
We know that the sum of the angles of a triangle is 180°.
⇒ 45 x° = 180° × 10°
⇒ 45 x° = 1800°
⇒ x° = 1800°/ 45°
∴ x = 40°
∴ The angles of the triangle are
