Question

straight angle is divided into the ratio of 3:2 then find the two parts(two angles

Answer 1

Consider the two angles as 3x and 2x
we know that straight angle is equal to 180°
so 3x + 2x = 180°
5x = 180°
x = 180\5
x = 36
therefore, the angles are
3x = 3×36 = 108°
2x = 2×36 = 72°

Answer 2

A triangle is a three-sided polygon. Triangles can be classified according to sides or according to angles: equilateral, isosceles and scalene, acute-angled, obtuse-angled and right-angled.

We use the notation △ABC to refer to a triangle with corners labelled A, B, and C.

A triangle is always 180°. 

3x + 2x = 180°

5x = 180°

x = 180\5

x = 36

⇒ the angles are

3x = 3×36 = 108°

2x = 2×36 = 72°
